A 0.56 kg rock is projected from the edge of the top of a building with an initial velocity of 7.57 m/s at an angle 53◦ above the horizontal. Due to gravity, the rock strikes the ground at a horizontal distance of 10.5 m from the base of the building. How tall is the building? Assume the ground is level and that the side of the building is vertical. The acceleration of gravity is 9.8 m/s^2. Answer in units of m.
