Solve the each part of given problem:

Problem: A small rock is thrown from the edge of the roof of a building with an initial velocity that has magnitude of v=20 m/s and a direction of 53.1 degrees above the horizontal. The rock hits the ground 4 seconds after it was thrown. Neglect air resistance.

Part A: What is the horizontal distance from the point where the rock was thrown to where it strikes the ground?

Part B: What is the height of the building?

Part C: What is the maximum height about the ground reached by the rock during its motion?

Part D: What is the speed of the rock just before it strikes the ground?

If possible just a brief explanation how you got the answer? Thanks in advance.
