Homework Help: Relativistic Mass of a Muon

  1. Aug 12, 2009 #1
    1. The problem statement, all variables and given/known data

    A muon traveling with negligible energy loss at v = 0.996c travels past a 4730m mountain. What is the relavitistic mass of the muon given the rest mass energy of 1.69 x 10^-11 joules???

    2. Relevant equations

    3. The attempt at a solution

    I think I should be using relativistic mass = m/sqrt(1-v^2/c^2). So m = 1.69 x 10^-11, however im unsure how to imput the other values into the equation. The answer i need to find is 2.1 x 10^-27. Thanks for your help.

    I do not understand the significance of the mountain to this question. Is there another question to this problem?

    It is incorrect to say that m = 1.69x10-11 Joules. Mass (in kg) is related to energy (in Joules) through what famous equation?
