Rectilinear Motion

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

    Find velocity and position as functions of time t for a particle of mass m, which starts from rest at x=t=0, subject to the following force functions.

    a) F=Fosin(ct)

    2. Relevant equations


    3. The attempt at a solution

    a) a=Fosin(ct)/m

    dv/dt = Fosin(ct)/m

    ∫dv = ∫Fosin(ct)/m dt

    v = -Fo(cos(ct))/mc

    integrate again

    x+ Fo(sin(ct))/(mc^2)

    This solutions manual says the answer is

    Look at your expression for v(t), remember that you want it to be at rest at t=0.

    I understand now, thanks
