A passenger in a helicopter traveling upwards at 20 m/s accidentally drops a package out the window. If it takes 8 seconds to reach the ground, how high to the nearest meter was the helicopter when the package was dropped?

  • physics -

    h = Hi + Vi t - 4.9 t^2

    0 = Hi + 20 (8) - 4.9(64)

    0 = Hi + 160 - 314

    Hi = 154 meters
