Homework Help: Finding horizontal velocity

  1. Oct 2, 2011 #1
    1. The problem statement, all variables and given/known data

    A car drives straight off the edge of a cliff that is 53 m high. The police at the scene of the accident note that the point of impact is 139 m from the base of the cliff. How fast was the car traveling when it went over the cliff?

    2. Relevant equations

    Distance=Acceleration*(Time^2) and any other distance, acceleration, velocity, time formulas.

    3. The attempt at a solution

    My attempt was to use the vertical distance and gravity to find the time it took to fall, and then somehow use that time (3.29s) to find the horizontal velocity. But I have no idea how to do that, and not even sure if I started it out right.

    Never mind, I had the right number (3.29s) but wrong idea. Just had to plug in that number in v=d/t to get the velocity... Durr.
