A box of bananas weighing 44.0N rests on a horizontal surface. The coefficient of static friction between the box and the surface is 0.500, and the coefficient of kinetic friction is 0.300.
A) What is the magnitude of the friction force if a monkey applies a horizontal force of 7.10N to the box and the box is initially at rest?
B) What minimum horizontal force must the monkey apply to start the box in motion?
C) What minimum horizontal force must the monkey apply to keep the box moving at constant velocity once it has been started?
