[Assume no air resistance] A pendulum is placed at 90º, parallel to the bench. The mass of the ball is 0.5kg, and the shortest distance between the ball and the bench is h meters. It is now released and hits a wooden block on the table at an angle of 60º and a height of q meters (to the bench). Given that it is an elastic collision and the ball stops upon hitting, for 0.25s. Assuming there is no friction between the wooden block and the bench, and the mass of the wooden block is m, express the velocity of the wooden block after 0.5 seconds of the collision in terms of m,h, and q.
