What is the magnitude of the impulse

  1. Jan 18, 2009 #1
    1. The problem statement, all variables and given/known data
    A proton has mass 1.7 x 10-27 kg. What is the magnitude of the impulse required in the direction of motion to increase its speed from 0.995c to 0.998c?

    2. Relevant equations

    3. The attempt at a solution
    (1.7 x 10-27 * 15.82 * 0.998 * 3x108) - (1.7 x 10-27 * 15.82 * 0.995 * 3x108)

    Re: Impulse

    Doesn't the gamma factor change quite a bit as well when you move from 0.995c to 0.998c?

    ya i accidentally typed 15.82 for the .995c but i ment to type 10.01. i tried that and its still wrong.

    edit: never mind, i just put the values in the calculator wrong lol.
