| AP PHYSICS B HELP :: a ball of mass .5 kg initially at rest is kicked directly
toward a fence from a point 32? A ball of mass 0.5 kg initially at rest is kicked directly toward a fence from a point 32 meters away. the velocity of the ball as it leaves the kickers foot is 20 m/s at an angle of 37 degrees above the horizontal. the top of the fence is 2.5 meters high. the kickers foot is in contact with the ball for 0.05 secondss. the ball hits nothing while in flight and air resistance is negligible.
a. determine the magnitude of the average 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 fence will it pass?
thank you!!
