1. The problem statement, all variables and given/known data what is the amplitude of the motion v=-6.54sin(20.1t) (mks units) angular frequency=20.1 2. Relevant equations v=wAcoswt 3. The attempt at a solution I think the wavelength is 6.54 since 20.1 is the frequency. v =6.2 m/s. I am missing time.
