Home Run Conundrum - The Solution

A home run is hit in such a way that the baseball just clears a wall 21m high, located 130 m from home plate. The ball is hit at an angle of 35° to the horizontal, and air resistance is negligible.

Find:
(a) the initial speed of the ball,
(b) the time it takes the ball to reach the wall, and
(c) the velocity components and the speed of the ball when it reaches the wall. (Assume that the ball is hit at a height of 1.0m above the ground.)
