Problem: A 2.0 kg brick is pushed horizontally off the top of a 12.0 m tall building. The brick lands 3.2 m from the side of the building.
Part A: Ignoring air resistance, what was the velocity at which the brick was pushed from the top of the building?
I want help to find the velocity at which the brick was pushed from the top of the building.
