Classical physic

    1. The problem statement, all variables and given/known data

    Now, consider the relativistic velocity addition formula:

    speed= (v+u)/(1+vu/c2.
    If v = u = 0.01c = 1 % of c, what is the relativistic sum of the two speeds?
    Express your answer as a percentage of the speed of light to five significant figures.

    2. Relevant equations
    the equation is given in the problem


    3. The attempt at a solution

    this is what i did speed= (1%+1%)/(1+(%*1%)/(100%2)

    and got 1.98020% dont know where im going wrong help!

    There is nothing wrong. Maybe you round the number quite too much. I got 1.9998%c, very close to 2% (=u+v) as expected.
