When you are operating a trimmer you have a mass of about 10 gr moving side to side. Let's assume that the amplitude of the motion is about 0.1mm, and that the frequency is f= 500Hz. So the blade will be vibrating: $$x(t) = X\cdot \sin(2\pi f t)$$ That means that is velocity will be: $$\dot{x}(t) = (2\pi f)X\cdot \cos(2\pi f t)$$ and the acceleration will be:...
