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

    a force of 5.02N acts on a 4kg object for 23.3s.
    momentum is 116.966 N*s

    2. Relevant equations

    what is the change in velocity?

    So you've found the momentum through impulse, how is momentum related to velocity?

    Impulse, I=F*t= change in momentum= mΔv.

    I guess now you know how to solve the problem.

    Cheers
