A ball is thrown from point A with initial velocity of 10 m/s at 45°, it reaches the maximum height and, on the return, it hits horizontal surface 2 m above the initial level and bounces back at 20° with the surface, with half of the speed of impact. 1. How long will it take to reach point B? 2. What is its velocity at the time of impact at point B? 45° 3. What is the horizontal distance of the ball from A to C (same level)? 4. What is its final velocity at point C? 2m C
