4. You let go of a 0.3kg ball from a height of 2m. When the ball bounces off the ground, it loses 15% of its energy as sound. a How high does the ball bounce back up after hitting the ground? b. What initial velocity would the ball need to be thrown dowwnward at so that it would bounce back up to a maximum height of 2m?
