Compute all parts of given question;
Question: A man stands on the roof of a 19.0m -tall building and throws a rock with a velocity of magnitude 24.0m/s at an angle of 38.0 degree above the horizontal. You can ignore air resistance.
Part A: Calculate the maximum height above the roof reached by the rock.
Part B: Calculate the magnitude of the velocity of the rock just before it strikes the ground.
Part C: Calculate the horizontal distance from the base of the building to the point where the rock strikes the ground.
