2. You go to the top of a building, drop a ball, and time its descent. It takes 14 seconds. You stand at the bottom of the building, throw the
ball up so it just reaches the top and falls back down again. What is
the time required for it to go up and back down again if air resistance
does not affect it?
Please I need help!
