To solve the problem step-by-step, we will break it down into two parts as specified in the question. ### Given: - Height of fall (h1) = 10 m - Height of rebound (h2) = 2.5 m - Acceleration due to gravity (g) = 10 m/s² (approximate value for simplicity) ### Part (i): Calculate the percentage loss of kinetic energy during the collision with the ground. ...
