Question:

A particle performs harmonic oscillations along the x axis about the equilibrium position x = 0. The oscillation frequency is w = 4.00 s-1. At a certain moment of time the particle has a coordinate Xo = 25.0 cm and its velocity is equal to Vxo = 100 cm/s. Find the coordinate x and the velocity vx of the particle t = 2.40 s after that moment.
