Since its starting and ending altitudes are the same, 0 feet, the time it returns to the ground is twice that of when it reaches the top of its trajectory. At the top of its trajectory, its vertical speed is 0 ft/s. That should get you started. Last edited by skipjack; March 7th, 2017 at 12:13 PM.

use Calculus. In this problem v0= 160 and s0= 0 while a is the downward acceleration is 32 feet per second per second. S+ o it will return to the ground when (32/2)t^2+ 160t= 0. That equation should be easy to solve. It has two solutions but it should be clear which is the one you want!
