A ball weighing 50g strikes a 1000 kg wall. According to Newton’s third law, what must be true regarding the force exerted on the ball by the wall?

The 5-kg cylinder is initially at rest when it is placed in contact with the wall b and the rotor at a. if the rotor always maintains a constant clockwise angular velocity v = 6 rad> s, determine the initial angular acceleration of the cylinder. the coefficient of kinetic friction at the contacting surfaces b and c is mk = 0.2.
