A package is dropped from a helicopter
from a height of 3,136 ft. If the equation
for height as a function of time is
h(t) = -16t2 + initial height where t is time
in seconds and h(t) is height in feet, how
many seconds will it take for the package
to hit the ground?

Answer:
14 seconds
Step-by-step explanation:
initial height =3136ft
h(t)=-16t^2 +3136ft
as the package hits the ground h(t)=0
-16t^2 +3136=0
-16t^2 =-3136
t^2 =196
t=√196
14 seconds or -14 seconds
