The coefficients of static and kinetic friction between a 482 Ncrate and the warehouse floor are 0.665 and 0.370, respectively. Aworker gradually increases his horizontal push against this crateuntil it just begins to move and from then on maintains that samemaximum push.

What is the acceleration of the crate after it has begun to move?Start with a free-body diagram of the crate.

The coefficients of static and kinetic friction between a 522 Ncrate and the warehouse floor are 0.715 and 0.420, respectively. Aworker gradually increases his horizontal push against this crateuntil it just begins to move and from then on maintains that samemaximum push.

-What is the acceleration of the crate after it has begun to move?Start with a free-body diagram of the crate.

5.29 - A 45.0-kg crate of tools rests on a horizontal floor. You exert a gradually increasing horizontal push on it, and the crate just begins to move when your force exceeds 313 N. Then you must reduce your push to 208 N to keep it moving at a steady 25.0 cm/s. (a) What are the coefficients of static and kinetic fric- tion between the crate and the floor? (b) What push must you exert to give it an acceleration of 1.10 m/s2? (C) Suppose you were per- forming the same experiment on the moon, where the acceleration due to gravity is 1.62 m/s. 1) What magnitude push would cause it to move? (ii) What would its acceleration be if you maintained the push in part (b)?

A crate of 33.5-kg tools rests on a horizontal floor. You exert agradually increasing horizontal push on it and observe that thecrate just begins to move when your force exceeds 332 N. After thatyou must reduce your push to 215 N to keep it moving at a steady21.0 cm/s.

Part C - What push must you exert to give it an acceleration of1.00 ?

215 N + (33.5 kg) * (1.0 m/s2) = 248.5 N

Part D - Suppose you were performing the same experiment on thiscrate but were doing it on the moon instead, where the accelerationdue to gravity is 1.62 . What magnitude push would cause it tomove?

(33.5kg) (1.01 coefficient of static friction) * (1.62 moongravity) = 54.8 N

Part E - What would its acceleration be if you maintained the pushin part C?

How do I solve part E? Thanks
