Problem: A dolphin jumps with an initial velocity of 13.0m/s at an angle of 41.0 degrees above the horizontal. The dolphin passes through the center of a hoop before returning to the water.
Part A: If the dolphin is moving horizontally when it goes through the hoop, how high above the water is the center of the hoop?
I need help to find how high above the water the center of the hoop.
