This golfer has been known to tell some extraordinary stories. Explain if each situation is possible using conservation of energy. Assume friction/air resistance ARE present. They hit a ball in a completely flat field, and the ball followed a parabolic trajectory (like in projectile motion). They measured the ball speed at takeoff to be 91m/s. When the ball landed 145m away, they measured their ball speed on landing to be 94m/s. They hit the ball along the ground. When the ball left the club, it was moving at 2m/s. When the ball went in the hole, it was moving at only 0.9m/s. The golfer claims that hitting the ball with a club that is four times as massive at the same speed makes the ball go two times faster off the tee. Note: Please solve the subparts
