3) The Ball and the rim roll down without slipping from tan inclined plane with an angle a(alpha). the initial speed of the ball is zero. what is the initial speed to be given to the rim so that the ball and rim travel the samedistance at the same time t ? the moment of the inertia of the ball with respect to the axis passing through its center lb = 2/5m (b) R^2 (b), while for the rim Ir = m (r) R^2 (r)
