Question: The equation s =16 t 2 + v 0 t + s 0 gives the height s , in feet above ground level, at the

The equation

s=16t2+v0t+s0

gives the heights, in feet above ground level, at the timet, in seconds, of an object thrown directly upward from a height

s0

feet above the ground and with an initial velocity of

v0feet

per second. A ball is thrown directly upward from a height of28feetabove the ground with an initial velocity of80 feetper second. Find the time interval during which the ball will be more than92feetabove the ground.
