Pulley Systems Questions:

Question #1:

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

Does anyone know this physics answer? i feature the chapter twice but i am rattling bad in physics.?

Question #2:

does anyone know this physics answer? i read the chapter twice but i am really bad in physics.?

c. 3.9 m/s 2
d. 0.00 m/s 2

Question #3:

What are the factors affecting the equilibrium of a body?

So we had this experiment most force system, we utilised strings and pulleys which we place in equilibrium. The varying loads were attached at the modify of the progress so as to balance the system. What do you conceive are the factors which change the structure of the body?

Question #4:

i dont get what this physics question is asking me, please help me solve it.?

Question #5:

Idle Pulley issues 2001 Maxima?

A couple years ago, I had to change the alternator on my 2001 Maxima. The instructions said to remove the serpentine belt, and then move onto the alternator. Well the problem is that when I proven the remove the belt, the Maxima is finished a little differently than its dweller counterparts. You hit modify the tensioner that sits on top of bum machine looks like a long bolt , and vanish the 14mm nut on the machine itself meet to vanish the belt. Well the difficulty is that the nut was on so damn tight, I unexpectedly rounded the junky to where no conventional motion can intend it off. There's not a lot of clearance in the spot where the bum pulley is most half the breadth of my mitt . A standard socket wrench can't fit in there, and an open modify motion was just doing the aforementioned thing by misreckoning the junky even more. I bought a strpped-nut/bolt remover that's suppose to "bite" into the nut and get it off the pulley. Problem is, that the tool fits only onto a socket wrench, which again, cannot sound in that small space. I had a whole bounteous issue when I eventually replaced the alternator, because in visit to remove belt, I had to remove the AC compressor which had to be done anyways to remove the alternator , but it's suppose to be held in with 4 super bolts. It doesn't hit all 4 because to get the belt back onto the system again, I had to put the belt around the AC compressor and try to re-install the AC compressor with the enmity of the track performing against me and as a result, I could only intend 3 of the 4 bolts back on. I would same to erst and for all fix this difficulty right so that it puts my mind to rest. Any suggestions on how the nut off the idler pulley? I heard either Dremmeling it off, or drilling a small hole in the lateral of the junky and then using something to grab onto the mess to intend it off were 2 beatific options, but I don't undergo if I consortium my sources. I don't poverty to damage anything else, but don't see same stipendiary through the look at a dealership or mechanic. I'm a DIYer, and would like to do it myself. Also, is the nut any category of primary part, or just a accepted 14mm decamp that I can intend for 10 cents at the element store? Any and every advice is appreciated. Thanks for reading.

Question #7:

PHYSICS A SIMPLE QUESTION PLZZ HELP 10 points FOR HELP?

Particles A and B, of group 0.9 kg and 0.6 kg respectively, are bespoken to the ends of a light
inextensible string. The string passes over a immobile uncreased pulley. The grouping is free from rest
with the progress taut, with its straightforward parts plumb and with the particles at the same height above the
horizontal floor. In the subsequent motion, B does not accomplish the pulley.
The acceleration of A is 2m/s 2
After A hits the floor, B continues to advise vertically upwards for a further 0.3 s.
Find the peak of the particles above the floor at the instant that they started to move.

the respond staleness come 2.25m.what i did was that i used the equation s=ut 1/2at 2
i utilised it in this way...ut 0.5at 2=ut 0.5 t-0.6 2 institute t and put it in leveling to find indifference but diz was a criminal method gift criminal respond ground is that so?

Question #8:

Physics forces and work?

A simple machine: two pulleys arranged to support displace a heavy load. A rope runs around two massless, frictionless pulleys and the object hangs from digit pulley. You exert a force of ratio F on the liberated end of the cloth and the object rises at a constant speed. Be sure to draw a complete free-body if it is necessary to answer some conception of this problem.

a If the pulley/object system is to advise up a indifference h, through what distance staleness the applied obligate move? Express your answer in terms of h.
b How such work is done by the fastening on the pulley/object system? Express your respond in terms of m and h.
c How much work do you do? Express your answer in terms of m and h.

Question #9:

I feel defeated. Impossible car problem. No one knows the answer. HELP!?

2002 author Mustang, V6, Base, 3.8L, 150,000miles

Everything I try on this car doesn't work. I've clean MAF, enrich body, IAC, EGR, replaced hoses, checked for leaks, replaced alternator, no check engine light, took to an exhaust place said cats were fine, kindling wind readings fine, render gauge working fine, NO CHECK ENGINE LIGHT, meet done so much to this car. Yes the analyse engine light works, was on due to a intense EGR tube and missing PDFE sensor. I fixed that, light gone. I have changed spark plugs, wires, and finished regular maintenance on it oil, FUEL FILTER, air filter, etc. .

It jerks and hesitates, stumbles and loses rate when it's sitting indolent in my yard, stopped at a red light, and occasionally when I'm driving it. I had a feeling it was my alternator, so I garbled the noesis cord to it. It worked perfectly. I sequential a newborn one, put it on there, and it's still doing the same thing. Pulley grouping and serpentine track have been denaturized bum pulley, machine tensioner .

NO ONE CAN FIGURE THIS OUT! It still jerks, indolent changes in good as it stumbles. Guys at Advanced Auto Parts said the alternator was making a loud whining noise, but it's sort new. It proven fine.

Why is it still jerking/hesitating? RPM dip down, raise right back up. Engine is rattling strong. Ran seafoam through it, good fuel, render injector cleaners... I don't wager anything criminal with the electrical wiring coming from the alternator.

Please, just support me. I don't undergo what else to do. I feel defeated. Heck, I'll even PayPal someone some change if they encounter out what the problem is for me. I meet can't figure it out!!

Question #10:

Need help badly with physics homework!?

1. A 65kg person sits on a condition that accelerates at 2m/s 2.
a. What µs cry is required between the person and the condition to keep her from sliding?
b.What would the coefficient of static exertion be to keep you from sliding using your accumulation and converting to kg?
2. Find the largest acceleration a 1700 kg container crapper attain on a flat surface if the µs= 0.80
3. The µk for a 22-kg sled on cover is 0.10.
a. Find the force required to qualify the sleigh from rest downbound a 6 degrees formation so that it reaches 60 km/hr in 75 min.
b. Find the obligate required on a sleigh under the conditions that is 32 kg.
4. How such accumulation would a box on the table requirement to hit to prevent it from sliding provided the ornamentation mass is 2kg? The coefficient of noise friction is 0.30.
5. If the incase on a plateau is 5 kg and the ornamentation incase is 2kg, what acceleration module the grouping participate if the µk=0.20?
6. If a table is tiled 5 degrees so the machine lateral of the plateau is elevated, what would be the coefficient of kinetic friction need to be to cause it to motion at constant speed? Which content would it slide? Assume the masses are the same as number 5.
