There is a bicycle on a bicycle stand We know that its rear

There is a bicycle on a bicycle stand We know that its rear wheel s moment of inertia around its axis is I 0 5 kg m and its radius is r 30 cm We speed up the wheel by repeatedly hitting it with a hand tangentially on its circumference in the direction of its rotation The speed of each hit in the rest reference frame is v 5 m s the mass of the hand is m 1 5kg the hand loses all its velocity in the reference frame of the point of impact after the impact the hand is moving around an elbow but we neglect rotation of the forearm If velocity of a point on the perimeter of then value of a 2B yl 10 a 9 the wheel after 10 hits be v a 1
