Question

A camera is accidentally dropped from a helicopter at a height of 4,096 ft. If the equation for height as a function of time is

h(t) = -16t^2 + initial height where t is time in seconds and h(t) is height in feet, how

many seconds will it take for the camera to hit the ground?

[?] seconds

Answer:

  16 seconds

Step-by-step explanation:

You want to find t such that h(t) = 0

  h(t) = -16t^2 +4096 . . . equation for height

  0 = -16t^2 +4096 . . . . .equation for height = 0

  16t^2 = 4096 . . . . add 16t^2

  t^2 = 256 . . . . . . . divide by 16

  t = 16 . . . . . . . . . . . take the positive square root

It will take 16 seconds for the camera to hit the ground.
