A ball of mass m is attached to a cord of length L
A ball of mass m is attached to a cord of length L, pivoted at point O, as shown in Fig. The ball is released from rest at point A, swings down and makes an inelastic collision with a block of mass 2m kept on a rough horizontal floor. The coefficient of restitution of collision is e=2/3 and coefficient of friction between block and surface is After collision, the ball comes momentarily to rest at C when cord makes an angle of θ with the vertical and block moves a distance of 3L/2 on rough horizontal floor before stopping. The values of μ and θ are, respectively,
