Abowl of mass .5 kg, initially at rest, is kicked directly towards a fence for my points 20 m away. the velocity of the ball as it leaves the kids foot is 17 m/s at the angle of 46° above the horizontal. the top of the fence is 6 m high. the kickers what is in contact with the ball for .04 seconds. the ball hits nothing while in flight and air resistance is negligible. the acceleration due to gravity is 9.8 m/s squared. determine the time it takes for the ball to reach the plane of the fence
