Problem # 2

2-D motion under influence of gravity

A ball, thrown with an initial velocity vo = 30 m/sec and angle = 70o from point A, makes contact with the wall at point B. Point A is a distance L=20 m away from the wall. Start with F=m*a in an x-y coordinate system and neglect air resistance.

  1. Determine the time the ball needs to travel from A to B
  2. Calculate the height H of point B
