Is Your Calculation of Simple Harmonic Motion Accurate?

[QUOTE="haruspex, post: 6487089, member: 334404"] ##100\pi## r/s is the angular velocity, which is constant. The question is asking for the maximum linear velocity, i.e. the maximum rate of change of x. See [USER=686233]@onatirec[/USER]'s advice above. The units are wrong for an acceleration, and if we correct the units to ##m/s^2## the number is wildly wrong. I want to know how you calculated it. It sounds like someone gave you the answer but you wrote it down wrongly, and don't know how to find it for yourself. Is that right? But where does the value of 0.02 r/s for w come from? Here's how this stuff works: ##x(t)=A\sin(\omega t+\phi)## Differentiate to find the velocity: ##v(t)=\frac{dx}{dt}=A\omega\cos(\omega t+\phi)## Differentiate again to find the acceleration : ##a(t)=\frac{dv}{dt}=-A\omega^2\sin(\omega t+\phi)## Do you understand those differentiation steps?
