Please help me , where do I start

A devious student leader at Renkluaf University, Yeleek Recrep, throws a water balloon downward at angle of 24.80 below the horizontal (see diagram) with an initial speed 36 m/s. The student releases the balloon from the tower, which is a height of 20 m above the ground. a. The student is throwing the balloon at the infamous ruffian faculty member Dr. Ffej Notgnirra, who stands defiantly 37 m away from the tower. Will the ruffian get doused? Show the calculations to support your answer. [Hint: The devious student gets only a small splash on the ruffian!] b. Suppose the crafty physics goddess, Eicarg Namttip, decides to apply her mad physics skills to the challenge of dousing the ruffian by changing the angle from 24.80 below the horizon to 24.8 degrees above the horizon while throwing her balloon at the same speed. The defiant ruffian refuses to move! What is the ruffian's fate, will Namttip douse him? Show the calculations to support your answer. [Hint: The physics goddess throws her balloon way over the ruffian's head.] C . Suppose the ruffian decides he is bored by this game and he wants to mock the physics goddess by daring her to throw another balloon in the same direction and with the same velocity. The ruffian secretly plans to catch the balloon and drink the water from the balloon as his victory toast. How far from the tower should the ruffian place his glass to catch the balloon
