Question 333448
An object is thrown upward from the top of a 160-foot building with an initial velocity of 48 feet per second. The height h of the object after t seconds is given by the quadratic equation h = -16t^2 + 48t + 160.  When will the object hit the ground?
------------
When h = 0
h = -16t^2 + 48t + 160 = 0
Solve for t
