Question 727017
A catapult is designed to launch extreme circus performers to ridiculous heights from a raised platform. After launch, the height of the performer in feet is given by h(t)=-16t^2+80t+32.  Where t is seconds after the launch. After how many seconds is the performer 100 feet above the ground?
-----------------
h(t)=-16t^2+80t+32
-16t^2+80t+32 = 100
Solve for t
There are 2 solutions, going up & coming down.
