Box and ball: Box of mass M is at rest on rough incline surface. The incline has angle d with horizontal. Ball on mass m is connected to the box via massless rope passing over frictionless massless pulley as it is shown on the figure. Coefficient of static and kinetic friction between incline and the box are us and / correspondently. It is known, that Us > MK and if something will help box start to move, it will not stop moving until it reach the pulley. Answer question below in terms M of g, a, M , m, MS, MK (not all may be necessary). HKg HS m (a) Box is at rest. Draw free body diagram of the box and the ball (b) Box is at rest. Find tension in the rope. (c) Box is at rest. Find friction force acting on the box (d) In this part of the problem, block M is moving up the incline. What is the acceleration of the box? (e) Find tension force in previous part
