A box of bananas weighing 45.0 N rests on a horizontal surface. The coefficient of static friction between the box and the surface is 0.400, and the coefficient of kinetic friction is 0.200.-If no horizontal force is applied to the box and the box is at rest, how large is the friction force exerted on the box?-What is the magnitude of the friction force if a monkey applies a horizontal force of 9.10 to the box and the box is initially at rest?-What minimum horizontal force must the monkey apply to start the box in motion?-What minimum horizontal force must the monkey apply to keep the box moving at constant velocity once it has been started?
