A carton of bananas weighing 350 newton rests on a, Ask an Expert

Academics

A carton of bananas weighing 35.0 Newton rests on a horizontal surface. The coefficient of static friction between the carton and the plane is 0.39, and the coefficient of kinetic friction is 0.22.

(a) If no horizontal force is applied to the carton and the carton is at rest, compute how large is the friction force exerted on the box?

(b) Find the magnitude of the friction force if a monkey applies a horizontal force of 6.1 Newton to the carton and the carton is initially at rest?

(d) Find what minimum horizontal force must the monkey apply to keep the carton moving at constant velocity once it has been started?

(e) If the monkey applies a horizontal force of 18.5 N, find the magnitude of the friction force and find what is the carton's acceleration?

frictional force N

acceleration m/s2
