The man stands 18 m from the wall and throws a ball at it with the speed of 15 m/s as shown in Figure Q2. He release the ball at an angle of 0 = 30° so that it strikes point B at the height of h1. The ball reached the maximum height at C. Q2 (а) Find the component of velocity in x-direction just before it hit the wall at point B. (b) Calculate the time of flight of the ball from A to B. (c) Determine the height of h1 when the ball reach and hit the wall at point B.
