Some smart physics person, help me out here.

A ball player hits a home run, and the baseball just clears a wall 18.5 m high located 140.0 m from home plate. The ball is hit at an angle of 32° to the horizontal, and air resistance is negligible. Assume the ball is hit at a height of 1.0 m above the ground.

a. What is the initial speed of the ball? Solve for time in the x-direction and substitute it in the formula for the vertical position.

b. How much time does it take for the ball to reach the wall? Solve using only the vertical component of the velocity or the horizontal component.

c. Find the velocity components and the speed of the ball when it reaches the wall.
