Hi, I've been working on this problem and I can't seem to get it right. I set it up in two steps. The first step I solved for the height using the final velocity as zero, then took that height and subtracted three to use as the displacement on the second step. Any help would be greatly appreciated. Here's the problem: A golfer hits a shot to a green that is elevated 3.0 m above the point where the ball is struck. The ball leaves the club at a speed of 18.1 m/s at an angle of 52.0˚ above the horizontal. It rises to its maximum height and then falls down to the green. Ignoring air resistance, find the speed of the ball just before it lands.
