Simple Momentum problem

  1. May 29, 2008 #1
    [SOLVED] Simple Momentum problem

    A particle initially has a speed of 0.47c.
    (a) At what speed does its momentum increase by 1%?
    .4747c
    (b) At what speed does its momentum increase by 10%?
    ____c
    (c) At what speed does its momentum increase by 100%?
    ____c

    To get the answer for part a, i just multiplied the speed by 1.01. I assumed that I would do the same, except 1.1 and 2 for parts b and c respectively, but the answers are not right. I have a feeling I'm just missing something but can't quite figure out what it is.

    What's the relativistic definition of momentum?
