Question

A ball is dropped from a height of 45m from the ground. The ball repeatedly bounces on the ground and eventually stops.If the ball looses 1/3of its speed each time it hits the ground. Then find for how long does the ball stops moving.Take g=10m/s.... BRAINLIEST ANSWER IS ON THE LINE

Answer 1

Thus a typical ball bounces to 60% of its original height because it stores and returns 60% of the energy it had before the bounce. ... When you drop a ball from a greater height, it has more kinetic energy just before it hits the floor and stores more energy during the bounce—it dents farther as it comes to a stop.
