During pre-season training of football team, the players are practicing punts by kicking balls in to an empty pool which is 3 meters deep.  For one of the kicks, the ball lands in the bottom of the pool at a horizontal distance of 38.1 meters, after having spent 2.2 seconds in the air.  [You can assume g '10 m/s2 ; Ignore the size of the ball; Ignore air resistance. Remember, velocity is a vector!]  (a)  Calculate the ball’s initial velocity.  (b)  Determine the highest point of the ball’s trajectory.  (c) Calculate the ball’s final velocity, as it hits the bottom of the pool.
