A ball is thrown towards a wall with an initial speed of 25.0 m/s, starting at 8.20 m above the ground. The height of the wall is 10.0 m and it is located 20.0 m from the launch point of the ball. You may assume projectile motion for the ball. (SEE DIAGRAM IN PICTURE BELOW) a) When the ball passes directly above the wall, how high above the wall is it? What is the velocity of the ball when it...
