A home run is hit in such a way that the baseball just clears a wall 21 m high, located 130 m from home plate. The ball is hit at an angle of 35° to the horizontal, and air resistance is negligible. (Assume that the ball is hit at a height of 1.0 m above the ground.)
(a) Find the initial speed of the ball.
_______ m/s
(b) Find the time it takes the ball to reach the wall.
_______ s
(c) Find the velocity components of the ball when it reaches the wall.
_____ x-component m/s
_____ y-component m/s
(d) Find the speed of the ball when it reaches the wall.
______ m/s
