A skydiver jumps out of a plane and her height above the earth can be measured by the equation h=-16t^2-8t+2880 where h is her height above the earth in feet and t is the time in seconds since she jumped How long does it take for the diver to reach earth if she doesn't open her parachute? Round to the nearest tenth of a second (one decimal place) What is the diver's height after 4 seconds? How long does it take for the diver to reach 1000 feet? Round to the nearest tenth of a second. (one decimal place) When the diver reaches 1000 feet, she deploys her chute, which changes the equation for her fall, The new equation is modeled by h=-0.025t^2+1000. How long after she releases the chute will it take for her to reach the ground?
