A ball is dropped from a height of 36 feet. The quadratic equation

d=1/2 gt^2

is used to calculate the distance (d) the ball has fallen after t seconds. The constant g is the acceleration of gravity, 9.8m/s^2. How long does it take the ball to hit the ground?


A ball in problem 2 is dropped again, from a different height. This time, it takes 3 seconds to hit the ground. How far does it fall?

  • Math -

    for 1.

    d= 36 ft
    g = 9.8
    find t.
    t=?
    plug it in and find the answer

    for 2.

    t=3
    g=9.8

    find d

    d=?
