    [SOLVED] thermal physics

    1. The problem statement, all variables and given/known data
    a) What is the total random kinetic energy of all the molecules in one mole of neon at a temperature of 305 K? I got 3801.83J

    (b) With what speed would a mole of neon have to move so that the kinetic energy of the mass as a whole would be equal to the total random kinetic energy of its molecules?

    2. Relevant equations


    3. The attempt at a solution
    I'm not sure what to do in order to solve for part b. Not to sure if i'm even looking at the correct equations. Any suggestions?
