A boy throws a ball with a horizontal speed of 2.5 m/s at a height of 0.8 m above the ground. The Coefficient Of Restitution between ball and ground is 80%.

Question

• Calculate the x− and y−components of the ball’s velocity, immediately after its first bounce. Correct numerical expressions (put in m/s) suffice for an answer, without calculating their final returns.
• Calculate the ball’s maximum height h, immediately after its first bounce. Express this answer (put in m) with an accuracy of three digits after the floating point.
