A particle performs harmonic oscillations along the x-axis about the equilibrium position x = 0. The oscillation frequency is ω = 4.00s-1 At a certain moment of time the particle has a coordinate xo = 25.0cm and its velocity is equal to vx0 = 100cm/*.
Find the coordinate x and the velocity vs of the particle t = 2.40s after that moment.
Let the general equation of *.H.M. be
Let us assume that at t = 0, x = x0 and vx = vx0.
Under our assumption eqns (1) and (2) given the sought x and vx if
Putting all the given numerical values, we get:
