## Homework Statement

A 22 kg block oscillates back and forth along a straight line on a frictionless horizontal surface. Find the oscillation frequency, if its displacement from the origin is given by

x(t) = (22.0 cm)·cos((25.0 rad/s)t + π).

## Homework Equations

angular frequency=sqrt(k/m)

period=2pisqrt(m/k)

period=1/frequency

## The Attempt at a Solution

okay so from the equation they gave us i think the 22.0 cm (0.22m) is the amplitude of the oscillation, and 25.0 rad/s is the angular frequency, and the pi is the is the phase angle. So I am trying to solve for oscillation frequency but I am not sure how to start the problem. Any solid help with trying to start this problem would be appreciated, Thanks!
