A football player is at the top of a 200 m high building. He decided to kick the ball (edge of the building) from rest giving it an initial velocity of 16 m/s at angle 600. Assume that there is no friction on the ball. (a) Use the conservation of energy to find the maximum height reached by the ball (b) Use the conservation of energy to find the magnitude of the velocity just before it hits the ground. (c) Use the kinematics equation for projectile motion to find (a) and (b). Are your results the same as (a) and (b) above? Which is more convenient for you, using kinematics for projectile or using conservation of energy?
