Good morning,I am stuck on a homework problem. It reads:"On a distant planet, golf is just as popular as it is on earth. A golfer tees off and drives the ball 2.10 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 40.2 m/s at an angle of 32 ° above the horizontal. When the ball lands, it is at the same level as the tee. On the distant planet, what are (a) the maximum height and (b) the range of the ball?"I figured out how to find the vector components, but I have no idea what to do next. Thank you in advance for your help!

Good morning,

I am stuck on a homework problem. It reads:

"On a distant planet, golf is just as popular as it is on earth. A golfer tees off and drives the ball 2.10 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 40.2 m/s at an angle of 32 ° above the horizontal. When the ball lands, it is at the same level as the tee. On the distant planet, what are (a) the maximum height and (b) the range of the ball?"

I figured out how to find the vector components, but I have no idea what to do next. Thank you in advance for your help!
