A man is pulling a 40.0 kg crate across a level floor with a horizontal force, and the coefficient of kinetic friction is ?k = 0.59 for the crate and the floor.

a) What is the normal force acting on the box?

b) What horizontal force must the man apply to get the crate to accelerate at 2.0 m/s2 ?

c) If he succeeds in maintaining this force and pulls the crate 15 meters, how much work has the man done?
