Homework Help: What happens to the maximum velocity if you double both Amplitude and period of a SHM

    what happens to the maximum velocity if you double both Amplitude and period of a SHM?

    the equation is

    x(t) = A cos (wt + f)
    v(t) = -A w sin (wt + f)

    f is phase constant, w = angular velocity

    i know if i double A and T, the first part of the v(t) equation will be like:
    -2A * 2pi/2T = -A * w, not changed, but what about that part in the sine ???

    the question ask if it is halved, quadrupled, unchanged, or doubled

    You're asked about the maximum velocity.That should happen when the sine is either +1 or -1 (abosolute value,nevermind the sense)...Therefore,it's not a factor to this problem...
