    Simple harmonic motion question!!

    1. The problem statement, all variables and given/known data
    A mass undergoing simple harmonic motion has a displacement of X = 0.5 m and V = 4 m/s at one time and x=.25 and V = -8. what is the period of this oscillation?


    2. Relevant equations
    X(t) = Acos (wt + phi)
    V(t) = -Awsin (wt + phi)


    3. The attempt at a solution
