On a distant planet, golf is just as popular as it is on earth. A golfer tees off and drives the ball 2.5 times as far as he would have on earth, given the same initial velocities on both planets. The ball is launched at a speed of 42 m/s at an angle of 54° above the horizontal. When the ball lands, it is at the same level as the tee.
(a) On the distant planet, what is the maximum height of the ball?
