A baseball is dropped from a tall building and takes 4.1 seconds to hit the ground. From what height was the ball dropped?

  • Physics -

    h=gt²/2

  • Physics -

    h = (1/2) g t^2
    = .5 * 9.81 *4.1^2
    = 82.45 m
    check
    how long to fall from 82.4 m
    82.45 = (1/2) (9.81) t^2
    t = 4.1 s check
