A 220 N trunk rests on the floor. The coefficient of static friction between the trunk and the floor is 0.41, while the coefficient of kinetic friction is 0.32. (a) Calculate the minimum horizontal force with which a person must push on the trunk to start it moving. (b) Once moving, calculate the horizontal force the person must apply to keep the trunk moving with constant velocity. (c) If the person continued to push with the force used to start the motion, calculate the acceleration of the trunk.
