One ball with mass m is connected at one end of a ropewhile the other end of the rope is fixed to the pin on the ceiling, with the length L. At first we keep the rope and ball still at the horizontal direction. Then we release the ball. a) Find the speed of the ball and tension force of the rope when the horizontal angle is 0.(3 points) b) At the bottom, the ball hits a box with mass M with full inelasticity. What the velocity after the collision? If such collision is fully elastic, what is the corresponding velocity?(3 points)
