You are playing raquetball at the rec center. When you are 10 m away from the wall you hit a ball 24 m/s towards the wall at an angle of 30 degrees. Ignore any affects due to air resistance.
Part A How long is the ball in the air before it hits the wall?
Part B How high above the launch point does the ball hit the wall?
