Question: A 0.48 kg rock is projected from the edge of the top of a building with an initial velocity of 11 m/s at an angle 49 degree above the horizontal. Due to gravity, the rock strikes the ground at a horizontal distance of 16.8 m from the base of the building. Assume the ground is level and that the side of the building is vertical. The acceleration of gravity is 9.8 M/s2.
Part A: How tall is the building?
Answer in units of m
