Problema Solution
A relief package is released from a helicopter at 1600 feet. The height of the package can be modeled by the equation:
h(t)=-16t+1600
where h is the height of the package in feet and t is the time in seconds. The pilot wants to know how long it will take for the package to hit the ground?
Answer provided by our tutors
The height of the package can be modeled by the equation:
h(t)=-16t+1600
The package hits the ground after some time t, t>0 for which h(t) = 0 that is:
-16t + 1600 = 0

........
t = 100 sec
t = 1 min 40 sec
The package will hit the ground after 100 seconds.
If we graph the function h(t)=-16t+1600 we can see the solution from the graph:
