    Will any one help me to solve this?
    A famous relation in physics relates moving mass (m) to the rest mass (m0)of a particle in terms of it's speed (v) and speed of light. A boy recalls the relation almost correctly, but forgets were to put the constant 'c' . he writes,

    m = m0 / (1-v2)1/2

    Guess were to put the missing 'c' ?
