Question

2. Kyle Lowry (from the Toronto Raptors) is making a 3 point shot from 6m away from the basket. The ball leaves his hands with a vertical speed of 8.5m/s at a height of 2.05m. The ball then hits the basket (but does not go in) which is 3.1 m high. a) Calculate the speed of the ball when it hits the basket. b) What is the maximum height reached by the ball after it bounces off the basket? (assuming no energy is lost) c) If the ball went in the basket and did not touch the rim, would the maximum height reached after it bounces off the ground (again assuming no energy is lost) be higher or lower than in part 2. Why?
