    I assume what I'll be posting is what you are looking for...

    Let the initial kinetic energy be E.



    It increases by 100%, or doubles, to become:



    Where E' = 2E

    Now, comparing the two:



    Now, momentum is given by:







    Substituting what we found earlier;



    Since this equals 2;





    Can you finish it now?

    Post what you get!
