A ball is connected to a 4 cm long string. Suppose you hold the free end of the string and make the ball spin on a table so that the trajectory lies in a horizontal plane. Suppose that the tangential speed of the ball is constant and its value is 16 cm/s. Compute the angular velocity of the ball. What is the period T of the rotation? Express the angular velocity in revolutions per minute. Suppose now that the ball with angular acceleration α = -1.04 rad/s2. How much space will it travel along the circle after it stops? In how much time will it stop? How many complete revolutions will the ball make before coming to a stop?
