Question

A factory worker pushes a crate of mass 28.1 a distance of 4.90 along a level floor at constant velocity by pushing horizontally on it. The coefficient of kinetic friction between the crate and floor is 0.243.

A) What magnitude of force must the worker apply?
Take the free fall acceleration to be = 9.80 .


B) How much work is done on the crate by this force?
Take the free fall acceleration to be = 9.80 .


C) How much work is done on the crate by friction?
Take the free fall acceleration to be = 9.80 .


D) How much work is done by the normal force?


E) How much work is done by gravity?


F) What is the total work done on the crate?
