A factory worker pushes a 31.0 kgcrate a distance of 6.5 m along alevel floor at constant velocity by pushing horizontally on it. The coefficient of kinetic friction between the crate and floor is0.25.

(a) What magnitude of force must the workerapply?
(b) How much work is done on the crate by this force?
(c) How much work is done on the crate by friction?
(d) How much work is done on the crate by the normal force?
(e) How much work is done on the crate by gravity?
(f) What is the total work done on the crate?
