Determine the speed of rock just before it hits the street

Reference no: EM13677586

A small rock is thrown vertically upward with a speed of 17.0 meter per second from the edge of the roof of a 26 meter tall building. The rock doesn't hit the building on its way back down and lands in the street below. Air resistance can be ignored.

Part A Determine the speed of the rock just before it hits the street?

Part B Determine how much time elapses from when the rock is thrown until it hits the street?
