A winning basketball shot in the last second of a game is launched with an initial speed of 12.2 m/s, 68 degrees above horizontal, and at a height of 2 m above the floor. The ball passes through the basketball hoop mounted at 3.05 m above the floor.
A. What is the ball's velocity at the highest point of travel?
B.What is the maximum height, above the floor, reached by the ball before it arrives at the basket?
C. How much time does the ball take to reach the basket after the ball is thrown?
D. How far from the basket, horizontally, was the ball released when the shot was made?
E. What is the magnitude of the ball's velocity as it passes through the hoop?

Please provide formulas that you use, I am so confused on these types of problems.
