(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The position of a mass oscillating on a spring is given by x(t) = (18.3cm)cos[(2.35s^-1)t] .

What is the frequency of this motion?

2. Relevant equations

X= Amplitude x Cos (2pi/T x time)

3. The attempt at a solution

I know that frequency= 1/Period, im trying to use f= 1/(2.35s^-1) but it doesnt seem correct. Also i've tried multiplying the amplitude by 2.... f= 1/(18.3cm)x2

Thanks
