A football is kicked at an angle ? = 37.0° with a velocity of 20.0 m/s. Calculate a) the maximum height, b) the time of travel before it hits the ground, c) how far away it hits the ground, d) the velocity vector at the maximum height, and e) the acceleration vector at maximum height. Assume the ball leaves the foot at ground level for simplicity.
