Homework Equations

The Attempt at a Solution

You would use the fact that falling from the ceiling to his hand mirrors his toss to the ceiling.
One is travel up - the other down
One starts at high speed and finished at zero speed, the other starts at zero speed and finishes at the same high speed.

 

[Quantum Mind]

Recall the equations for motion, time and displacement and see which one fits. For that you have to see what values you know and what you do not know.
