Q RE Momentum from F in component form

  1. Oct 26, 2005 #1
    I am having some trouble figuring out where to start with this problem:

    The force on a particle of mass m is given by:

    F= 26i – 12t^2j

    where F is in N and t in seconds.

    What will be the change in the particle’s momentum between t=1s and t=2s?

    Can anyone point me in the right direction?

    The area under a force curve is equal to the change in momentum

    OK, so maybe this is where I'm having difficulty. From what I can gather, figuring the area under a curve requires some knowledge of integrals; something I haven't got to yet in Calc class.

    Is this assumption correct? Assuming it is, is there a way to do it without using integrals?
