Q2
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 hi. The ball reached the maximum height at C.
(a)
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 hị when the ball reach and hit the wall at point B.
(d)
Find the magnitude and direction of the ball just before it hit the wall at point B.
(e)
Determine the maximum height of h, and the horizontal distance of x.
