### A stunt double jumps from a plane that is 1500 ft above the ground. Function h= -16t^2 + 1500 gives the stunt doubles height "h" in feet during the free at "t" seconds.

A. How long is the stunt double in free fall if he opens his parachute at 1000 ft.

B. How long is the stunt double in free fall if he opens his parachute at 950 ft.

C. What is a reasonable domain and range for the function "h".

# A.

he will free fall for 5.59 seconds if he opens parachute at 1000ft above the ground.

# B.

He will free fall for 5.86 Seconds if he opens parachute at 950 ft above the ground.
