A 0.41 kg rock is projected from the edge of the top of a building with an initial velocity of
12.5 m/s at an angle 58◦
above the horizontal.
Due to gravity, the rock strikes the ground at
a horizontal distance of 17.7 m from the base
of the building. Building
17.7 m

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

.
Answer in units of m.
