Kinetics after car left the cliff.

  1. Oct 18, 2009 #1
    1. The problem statement, all variables and given/known data
    A car of mass m = 1515 kg is pushed off a cliff of height h = 26 m. If the car lands a distance of 14 m from the base of the cliff, what was the kinetic energy of the car the instant after it left the cliff?



    2. Relevant equations



    3. The attempt at a solution Don't even know where to begin because this is a kenetics problem.

    You need to know the velocity of the car to calculate it's kenitic energy. How can you find the velocity of the car the instant it left the cliff.

    Hint: You'll need to use the kenimatic equations you already learned.

    It said to find the kinetic energy after it left the cliff and not the velocity. I calculated the velocity to be 22.6m/s using the V^2=v_o^2-2(g)(x_f-x_i). Is this wrong?
