A ball of mass 0.6 kg, initially at rest, is kicked directly toward a fence from a point 20 m away, as shown below.
The velocity of the ball as it leaves the kicker's foot is 18 m/s at angle of 58? above the horizontal. The top of the fence is 10m high. The kicker's foot is in contact with the ball for 0.05 s. The ball hits nothing while in flight and air resistance is negligible. The acceleration due to gravity is 9.8 m/s^2
1.Determine the magnitude of the average net force exerted on the ball during the kick.
2.Determine the time it takes for the ball to reach the plane of the fence.Answer in units of s.
3.How far above the top of fence will the ball pass?
4.What is the vertical component of the velocity when the ball reaches the plane of the fence?
