The movement of a particular piston of mass 0.85kg may be modeled with a simple harmonic. Given that its acceleration is 8m/s when 10cm from the mid position. Find the period of the motion??

I found velocity to = 1.26m/s, but I am not even sure if i need to calculate the velocity.

a=-(2πf)2x

We have a (= 8 m/s)
We know 2π (constant)
And we know x (= 10cm)

Rearrange to find f.

Period = 1/f
