If a car drives off a 40 m high cliff with a horizontal velocity of 15 m/s, how far from the base of the cliff will the car strike the fround? Could someone help with the equation, please

  1. How long does it take to fall 40 m?

    h= 1/2 g t^2
    solve for t.

    Now, given that time in the air, how far did the car travel horizontally?
    distance= 15*t

  2. So I say:
    40 m = 1/2 (9.8) * t^2
    40/4.9 = 8.16(t^2)
    sqrt of 8.16 = 2.86 = time
    15 * 2.86 = 42.9 for how far from the base of the cliff the car stuck the ground

    Is this correct?
    Thank you for helping-
    I'm homeschooled and trying to learn Physics on my own
