A ball is kicked directly toward a fence from a point x=32 m away. the velocity of the ball as it leaves the kickers foot is 20m/s at an angle of 37 degrees above the horizontal. the top of the fence is h=2.5m hight. the ball hits nothing while in flight and the air resisitance is negaliglable.
(a) Determine the time it takes for the ball to reach the plane if the fence.
(b) Determine the maximum hight of the ball during its flight.
(c) Will the ball hit the fence? if so, how far below the top of the fence will it hit? If not, how far above the top of the fence will it pass?
