Physics Pulleys Questions:

Question #1:

free body diagrams, calculate acceleration?

The plateau is frictionless. Take mass1 as 5kg and mass2 as 10kg and coefficients of friction to be static= 0.4 and kinetic=0.6
the picture looks like this but instead of meet digit block at A there's block m2 on the lowermost and block m1 on top

find the maximum speed of mass1?

i'm rattling confused as to how i cipher this.. i have to solve symbolically
and how do i undergo if both masses qualify together or if one accelerates faster than the other?
there's three masses though, there's accumulation 1 and mass2 on the table and mass 3 hanging off the table..
i'm not given the mass3
so i'm guessing i hit to solve symbolically? and m2 is adjoining to the string
m1 is sitting on crowning of m2
oh ok, also how would i encounter is the maximum accumulation of mass3 if mass1 moves on mass2 without slipping?

Question #2:

physics homework really need help please!?

1 The pilot of a small form finds that the airfield where he intended to realty is opaque in. He flies 40 miles west to another airfield to encounter that conditions there are too icy for him to land. He flies 30 miles at 15° easterly of south and is eventually healthy to land at the ordinal airport.
a How farther and in what content staleness he control the incoming period to go direct to his example destination?
blank? mi at blank? ° north of east
b How some player miles beyond his original grace plan has he flown?

2 For the train in the amount below, find the cipher velocity between 3:14 P.M. when the condition is at 3 km easterly of the origin and 3:26 P.M. when it is 5 km easterly of the origin. direction?

3 digit blocks are connected by a lightweight, flexible cord that passes over a frictionless pulley.
a If m1 = 3.1 kg and m2 = 5.2 kg, what are the accelerations of apiece block?

b What is the tension in the cord?

Question #3:

Need help on a physics problem?

1.
Stan raises a 1040 N piano a indifference of 5.00 m using a ordered of pulleys. Stan pulls in 20.5 m of rope.

a How such effort obligate would Stan apply if this were an saint machine?

b What force is utilised to equilibrise the exertion force if the actual effort is 340 N?

c What is the work output?

d What is the input work?

e What is the mechanical advantage?

Question #4:

Anyone Good at Math/Physics?

The wheel and bespoken pulley rotate about the fixed dig at O and are driven by the belt as shown. At a certain fast the rate and speed of point A on the belt are 2 ft/sec and 6 ft/sec 2 respectively, both in the direction shown. Calculate the magnitude of the amount speed of saucer B on the wheel for this instant. Observe that the linear change of saucer A on the track and the irrelevant motion of a saucer on the 4 in. radius circle are identical and that and for the symmetric lines to all points on the rotate are the same.

I am really confused by this problem. Do I meet cipher for tangential acceleration? Can someone give me whatever hints or walk me finished this I'd rattling appreciate the help. Thanks a ton in advance!

Question #5:

Another physics question?

I seem to be stupid with this stuff. If someone can support me with this and show me how to do it, I'd rattling appreciate it. Thank you in advance. :

In the Atwood machine m sub 1 = 2.00 kg and m change 2 = 7.00 kg. The group of the machine and progress are worthless by comparison. The pulley turns without friction, and the string does not stretch. The lighter goal is free with a sharp near that sets it into change at v change i = 2.40 m/s downward. a How farther module m change 1 move below its initial level? b Find the velocity of m change 1 after 1.80 s.

Question #6:

Need help on physics pully problem?

Two objects with group of 3.90 kg and 5.20 kg are connected by a light progress that passes over a frictionless pulley.

a Determine the enmity in the string.

b Determine the speed of each object.

c Determine the indifference each goal will move in the first second of motion if both objects move from rest.

Question #7:

The rate at which work is done is called energy ?

True or simulated physics questions.
When the respond is false , gratify state why:

15. The rate at which work is done is called energy

16. When we circularize an goal crossways a room without lifting it or movement it down we do no fleshly work on it.

17. In physics, the amount of work done on an object is the creation of the force exerted on the object times the instance the object moves.

18. The energy an object has by morality of its change is titled its kinetic energy.

19. The forcefulness an goal has by virtue of its positioning is titled its potential energy.

20. Energy transforms from digit form to another with no net loss or gain.

21. The machine is a figure for multiplying obligate or changing the content of force.

Question #8:

true or false physics questions. very simple, please help!?

When the answer is false , gratify land why:

15. The rate at which work is done is titled energy

16. When we carry an goal across a shack without lifting it or movement it downbound we do no physical work on it.

17. In physics, the amount of impact done on an object is the creation of the obligate exerted on the object times the instance the goal moves.

18. The forcefulness an goal has by morality of its change is called its kinetic energy.

19. The forcefulness an goal has by morality of its positioning is titled its possibleness energy.

20. Energy transforms from one modify to added with no net expiration or gain.

21. The machine is a device for multiplying force or changing the content of force.

Question #9:

Physics question on Force and Pulleys?

A hanging mass, M1 = 0.18 kg, is attached by a reddened progress that runs over a frictionless machine to the front of a mass M2 = 0.47 kg that is initially at rest on a frictionless table. A third accumulation M3 = 0.71 kg, which is also initially at rest on a frictionless table, is attached to the backwards of M2 by a light string.
A Find the ratio of the acceleration, a, of accumulation M3.
B Find the tension in the progress between group M1 and M2.

Question #10:

Physics help please! Much appreciated all you geniuses out there!?

Does anyone undergo this physics answer? i read the chapter twice but i am rattling intense in physics.?

a. 2.0 m/s 2
b. 5.3 m/s 2
c. 3.9 m/s 2
d. 0.00 m/s 2
