(a) What magnitude of force must the worker apply?
(b) How much work is done on the crate by this force?
(c) How much work is done on the crate by frication?
(d) How much work is done on the crate by normal force?
(e) How much work is done on the crate by the gravity?
(f) What is the total work done on the crate?
A factory worker pushes a 29.2kg crate a distance of 4.1m along a level floor at constant velocity by pushing downward at an angle of 28* below the horizontal. The coefficient of kinetic friction between the crate and floor is 0.25.

A factory worker pushes a 30.4 kg crate a distance of 5.0 m along a level floor at constant velocity by pushing downward at an angle of 31 ∘ below the horizontal. The coefficient of kinetic friction between the crate and floor is 0.26.
