A bouncy ball was horizontally thrown at A with an initial velocity of u = 14.5 m/s to a ravine as seen in the image. The ball then bounces at the bottom of the ravine, B, wherein it bounces up and lands at a horizontal distance R= 40.0 m, C from A. Y naught = 47.0 m and y1 = 18.0 m. 1) How long did it take for the ball to reach B from A? 2) What is the horizontal distance between B and A? 3) What was the speed of the ball just as it landed at B? 4) the ball bounces at B with the same speed it had before it landed. How long did it take for the ball to reach C from A? 5) At what speed must the ball be thrown from A for it to reach C without bouncing?
