    Need help solving an equation of motion of type m x'' = F(t)

    A particle of mass 3 kg, initially at position y(0) = 2 and moving with velocity v(0) = 4) is subject to the exponential driving force F(t) = 2e^(-3t)
    Find an expression for y(t).
    Any help would be greatly appreciated

    Re: Need help solving an equation of motion of type m x'' = F(t)

    m x" = F(t) = 2e^{-3t}

    So
    x" = \frac{1}{m} \cdot  2e^{-3t}

    What is the integral of e^{-3t} ?
