## Homework Statement

I am given the attached graph (excuse my abysmal homemade graph!). On the y-axis, I presume that it is displacement (x). The x-axis is time. This graph looks like SHM, but I could be wrong! The graph rises from 0 to 2 every 2 seconds, and drops back to 0 on the y-axis for 2 seconds before repeating the cycle. The problem asks to find angular velocity based on the graph. I am given the choices of 2.0 rad/s, 0.5 rad/s, 1 rad/sec, or none of above.

## Homework Equations

This graph looks like SHM, but I could be wrong!

## The Attempt at a Solution

I really have no clue how to derive angular velocity based on this graph. I am guessing you have to find tangential velocity from the graph and from there determine angular velocity using the formula v(tangential) = ω r. Am I on the right track? Again, please excuse the poor graph. :)
