2. A man stands on the roof of a 15.0-m-tall building and throws a rock with a velocity of magnitude 30 m/s at an angle of 33° above the horizontal. You can ignore air resistance. Calculate A) the maximum height above the roof reached by the rock; B) the magnitude of the velocity of the rock just before it strikes the ground; and C) the horizontal range from the base of the building to the point where the rock strikes the ground.
