A smoke jumper jumps from a plane that is 1900 ft above the ground. The function h=-16t^2+1900 gives the jumper's height h in f
eet 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?
