A stockroom worker pushes a box with mass 11.2 kg on a horizontal surface with a constant speed of 3.40 m/s . The coefIficient of kinetic friction between the box and the surface is 0.21.
a. What horizontal force must the worker apply to maintain the motion?
b. If the force calculated in part (a) is removed, how far does the box slide before coming to rest?
