## Homework Statement

A particle on a spring moves in simple harmonic motion along the x axis between turning points at x1 = 100cm and x2 = 140cm.

[1] at which of the following positions does the particle have max speed?

100cm, 110cm, 120cm, some other position, or same greatest value occurs at multiple points?

.... the questions move on to max acceleration, max net force, and such

## Homework Equations

## The Attempt at a Solution

I know the max speed occurs at x = 0, and when the motion reachs +- A, i know accerleation and net force are max.

But I don't get the question, please help me explain this

**between turning points at x1 = 100cm and x2 = 140cm**

let say I have a simple harmonic motion x in the y-axis, t in the x-axis.

Thanks
