On a distant planet, golf is just as popular as it is on earth. A golfer tees off and drives the ball 4.7 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 40 m/s at an angle of 30° 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?
(b) On the distant planet, what is the range of the ball?
