A smoke jumper jumps from a plane that is 1700 ft above the ground. The function h=-161² + 1700 gives the jumper's height h in feet during the free fall at t seconds.
a. How long is the jumper in free fall if the parachute opens at 1000 ft?
b. How long is the jumper in free fall if the parachute opens at 930 ft?
c. What is a reasonable domain and range for the function h?
a. The jumper is in free fall fors if the parachute opens at 1000 ft.
(Round to two decimal places as needed.)
