Question #2:

Physics: Keeping System Mass Balanced in a Lab?

So for you Physics superstars out there - I requirement whatever help. If you know exactly what I'm conversation about, meet feature the TL;DR conception at the modify of this

We fresh performed a work on how the Force affects the speed of a system. We used a mathematician Dynamics System a cart with a progress bespoken to it flat which is hooked on to a pulley a lowercase spinning wheel that converts the flat enmity in the string to plumb tension, with a accumulation crooked onto the end.....so when you permit go of the cart, the accumulation falls, making the cart accelerate.

Anyways, I forgot how we performed the lab...we did criminal the prototypal time. I undergo the pedagogue put a lot of emphasis on ownership the "system mass balanced." There were digit places where we placed masses: on crowning of the cart and at the end of the string. We tested the following grouping masses: 20g, 50g, 100g, and 200g. For example, for the 20g test, we put a 20g accumulation on the end of the string, and for the 100g test, we place a 100g accumulation on the end of the string.

HERE'S THE PROBLEM: Every time we performed each of the mass tests 20g, 50g, 100g, 150g, 200g , we had to switch discover the accumulation on the end of the string with digit of the group on crowning of the cart to ready the "system mass balanced." For example, After we complete the 20g effort and were about to advise on to the 50g test, we had to take the 20g accumulation soured of the end of the string, place it on the cart, verify the 50g mass, and place it on the end of the string. Throughout every of our trials, we never added or took absent some mass from the "system."

WHAT I DON'T KNOW is how such accumulation we had on the cart. So when we had the 100g accumulation on the end of the progress for the 100g test, how much mass was on the cart?

My only surmisal is that the entire grouping mass was 520g all of the masses compounded because that would earmark for each of the individualist masses 20, 50, 100, 150, 200 to be healthy to be settled on the end of the string, and ease hit accumulation on the cart. Is that the answer? Is it as simple as that? I just seemed to have blanked that conception out.



TL;DR we did a lab in physics: "How does the force affect the speed of the system." We did 5 tests: 20g, 50g, 100g, 150g, 200g. After apiece test, we took the mass that we just proven off of the end of the string, place it back on to the cart, took the next accumulation we were going to test soured of the cart, and put it on the modify of the string. During all 5 tests, we never additional or took away some accumulation from the "system." By "system," I stingy every of the mass from the cart and the modify of the string combined.

Thanks!

Question #3:

Physics question best answer ten points?

I don't see how to respond gain force/pulley questions for example:

a 2000kg plane rises at a constant velocity/ Suspended from beneath the form by a cable is a 150kg container of relief supplies.

what is the upward lift force?

what if the plane and container accelerated ascending at 2.5m/s/s, what is the displace force?

Calculate the upward force the cable from which the container is suspended exerts on the container when it has the acceleration above.

I don't requirement to encounter the respond but just exhibit me the calculations, I crapper plug it in later.

Question #4:

give me three examples of a simple machine?

one warning of a lever digit a pulley and digit a wheel and axle
the examples have to be anything but a knob a rotate delve a substantially and a act
give me the goal and tell me the think ground that object is a simple organisation explain how the goal entireness in the simple machine and how the object would work without it !!!

simulacrum gesture !!!

Question #5:

Two Masses Hanging on a Massive Pulley?

A machine with accumulation Mp and a length Rp is bespoken to the ceiling, in a somberness earth of 9.81 m/s2 and rotates with no friction most its pivot. Mass M2 is large than mass m1. The quantities Tn and g are magnitudes.
..... t3
....O
.t2 .. t1
.m2.
......m1

Select T-True, F-False, G-Greater than, L-Less than, E-Equal to. For example, if the first is T, the second L and the rest E, enter TLEEEE .
A m1g M2g Mpg is ..... T3.
B T2 is ..... M2g.
C The ratio of the acceleration of M2 is ..... that of m1.
D T2 is ..... T1.
E The center of mass of Mp M1 M2 does not accelerate.
F T3 is ..... T1 T2.

Question #6:

Physics - Statics vs. Dynamics?

Just a quick question on the direction of force vectors in statics and dynamics. Somehow, i conceive the direction of force vectors in statics is such assorted than the direction of force vectors in dynamics. For example, lets say you have a accumulation ornamentation by a rope that is bespoken to a machine neglecting the exertion in the machine .
Now if this accumulation was static, the assets of the forces in the y-direction would be F = T - mg = 0. However, if the accumulation was dynamic, meaning it was agitated downward, the assets of the forces in the y-direction would be F = mg - T = ma.
My question is ground do the signs directions modify on "mg" and "T" in both cases? Shouldn't they be the same in either case? I think the assets in the forces in the y-direction should be F = T-mg = 0 and F = T-mg = ma in both scenarios. Is there some difference? Thanks.

Question #7:

Find the mass of the pulley?

I hit an example of an Atwood machine, but I am having whatever troubles. Here's the problem: The two mass m1 = 5.0 kg and m2 = 3.0 kg in the Atwood's machine are free form rest, with m1 at a height of 0.75m above the ground. When m1 hits the connector its pace is 1.8m/s. Assuming that the pulley is a uniform disk with a radius of 12 cm, encounter the mass of the pulley.

Question #8:

Anyone remember a chain reaction type game? Ex. hammer hits see-saw, see-saw hits ball, ball rolls down ramp.?

It was a concern activity type mettlesome just as described. You had assorted levels and or tasks to complete and you had different tools to opt from. For example, hammers, pipes, balls, trampolines, sprockets, foam bands, pulleys,...etc. All kinds of things. And you necessary to make the machine impact in visit to go to the next level. Anyone remember that??

Question #9:

if a surface speed of a pulley is 3250 feet per minute, find its diameter when running 250 RPM?

could someone gratify help me with this digit problem.
i'm trusty i could amount the rest of the homework discover if someone helps me with this as an example. \
thank you in advance.

Question #10:

Newton's second law of motion lab question?

The lab I am currently doing in collection makes significance to me on paper, but i am confused when i compare my experimental acceleration to the theoretical acceleration.

here's what the work looks like. a cart with additional weight is adjoining by a progress and pulley to a weight hanging over the bounds of a table. as the weight over the plateau is released, the cart is pulled by a obligate equal to the mass of the weight times the speed of gravity, F=MA. assorted time trials are conducted with a unceasing distance the cart travels.

the part that confuses me is with the leveling "theoretical acceleration = mass of coefficient in grams / mass of everything in system ". the answers i get for academic speed are significantly smaller than the empiric acceleration using equation x=.5 9.8 t 2 . also, the obligate in newtons = 15 9.8 or 147.

for example. the 15g weight pulls a 1.5629kg total-weighted system. it takes 3.459 seconds to movement .68 meters. the academic speed is .015/1.5629 = .0096 m/sec 2 . the empiric was institute to be .1137 m/sec 2. .5 9.8 3.459 2 = .1137 .

what am i doing criminal to find the theoretical acceleration? it should be LARGER than the empiric speed due to friction, correct?
