124) A catapult is designed to launch circus performers from a raised platform. After launch, the height of the performer in feet is given by h(t) = – 16t + 80t + 32 where t is seconds after launch. After how many seconds is the performer at ground level? Round to the nearest tenth of a second. hft)-(1ut+80t+32) h(t)=-16(²-St-2) A-30
