Consider the solution tothe harmonic oscillator given above by x(t)=Ccos(wt−v) Prove tha tx(t0)=x(t0+2piw) In other words, the solution has the same value at time:t0 and at time:t0+2piw regardless of what value we have for ?0. The value 2piw is then the period T of the harmonic oscillator.

The displacement of an oscillating mass is given by x(t) = 30 cos( 2 t ). At time t = 2π s, what is the velocity of the mass in m/s?
12–3. A particle travels along a straight line with a velocity v = (12 – 32) m/s, where t is in seconds. When t = 1 s, the particle is located 10 m to the left of the origin. Determine the acceleration when t= 4 s, the displacement from t =0 to t = 10 s, and the distance the particle travels during this time period.
