Question

The displacement of a particle at t = 0.25 s is given by the expression x = (4.0 m) cos (3.0 p t + p), where x is in meters and t is in seconds. Determine(a) the frequency and period of the motion, (b) the amplitude of the motion, (c) the phase constant, and(d) the displacement of the particle at t = 0.25 s.
