A small rock is thrown vertically upward with a speed

Reference no: EM13551728

A small rock is thrown vertically upward with a speed of 12.0 from the edge of the roof of a 36.0 tall building. The rock doesn't hit the building on its way back down and lands in the street below. Air resistance can be neglected.

Part A What is the speed of the rock just before it hits the street? Express your answer with the appropriate units

Part B How much time elapses from when the rock is thrown until it hits the street? Express your answer with the appropriate units.
