A ball player hits a home run, and the baseball just clears a wall 21.0 m high located 150.0 m from home plate. The ball is hit at an angle of 34.0° to the horizontal, and air resistance is negligible. Assume the ball is hit at a height of 1.0 m above the ground and that upward is positive.
(a) What is the initial speed of the ball?
(b) How much time does it take for the ball to reach the wall?
(c) Find the velocity components of the ball when it reaches the wall.
m/s (x-component)
m/s (y-component)
Find the speed of the ball when it reaches the wall.
