Kinetic Energy Question

  1. Jul 13, 2008 #1
    1. The problem statement, all variables and given/known data
    A car witha mass of 1500 kg has a Kinetic Energy of 1,400,000 Joules. What is its velocity?

    2. Relevant equations
    I would assume that (K.E.=1/2 x m x v 2) could be used.

    3. The attempt at a solution

    I am not exactly sure how to attempt this question. Do we try to make velocity by itself in the above equation? I am not quite sure how to go about that.....

    Yes, that's how you solve for v, isn't it?
