You throw a ball with a speed of 25.0 m/s at an angle of 40.0degrees above the horizontal directly toward a wall. The wallis 22.0 m from the release point of the ball.
a.) How long does the ball take to reach the wall?
b.) How far above the release point does the ball hit thewall?
c.) What are the horizontal and vertical components of itsvelocity as it hits the wall?
d.) When it hits, has it pased the highest point on itstrajectory?
