A ball falls from a height h and strikes the ground. Immediately after bouncing, the ball leaves the ground with velocity vx = 0.58 m/s and vy = 4.25 m/s. = (a) How high will the ball bounce? (12 marks) (b) How far will the ball travel horizontally before hitting the ground again? (8 marks) (c) If the coefficient of restitution between the ball and ground is 0.75, what height was the ball originally dropped from? (5 marks)
