What equations do I use to solve this?

    1. The problem statement, all variables and given/known data

    A ball of mass .5kg, initially at rest, is kicked directly toward a fence from a point 32 meters away, as shown above. The velocity of the ball as it leaves the kicker's foot is 20m/s at an angle of 37 degrees above the horizontal. The top of the fence is 2.5m high. The kicker's foot is in contact with the ball for .05 second. The ball hits nothing while in flight and air resistance is negligible.

    a. Determine the manitude of the avg net force exerted on the ball during the kick.

    b. Determine the time it takes for the ball to reach the plane of the fence.

    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?
