A factory worker moves a 23.0kg crate a distance of 4.90m along a level floor at constant velocity by pushing horizontally on it. The coefficient of kinetic friction between the crate and the floor is 0.250
Part A What magnitude of force must the worker apply?
Part B How much work is done on the crate by the worker's push?
Part C How much work is done on the crate by friction?
Part D How much work is done by the normal force?
Part E How much work is done by gravity?
Part F What is the net work done on the crate?
