A man stands on the roof of a 17.0 m tall building and throws a rock with a velocity of magnitude 24.0 m/s at an angle of 33.0° above the horizontal. You can ignore air resistance. (a) Calculate the maximum height above the roof reached by the rock. (b) Calculate the magnitude of the velocity of the rock just before it strikes the ground. (c) Calculate the horizontal distance from the base of the building to the point where the rock strikes the ground. Ok I started out by doing 24sin(33) and 24cos(33). Then I did 17=0+23.99t+1/2(-9.8)t^2. I got wrong answers for all 3 parts. I got 23.99 m for part A, for part B I got 44.21 m/s, and part C i got apprx 30 m. Can someone confirm my answers and not just show the answer alone, i need to know HOW to do it.
