## Homework Statement

I have some problem where I have measured angular velocity data. This measurements are not equally spaced, meaning there were taken after some (variable) delay passed.

I need to find what is the angular acceleration at each point of measurement.

## Homework Equations

ummmm I don't know... perhaps α= Δω/Δt??

## The Attempt at a Solution

So I have some measures like

Code:

```
Time(μs) Speed(rad/s) Accel(rad/s^2)
------------------------------------------------------------
15115 2.078458
24184 3.464097 91.67310552 ???????
31238 4.453629
37207 5.263176
42474 5.964667
```

I have tried accel=(speed2-speed1)/(time2-time1) (see the 91.67310552)

Is this flawed??

The graphic of the speed show a almost linear increase of speed (until it becomes constant), so by theory this should give a constant acceleration and then 0 right? But my calculations become kind of crazy after a whileand give a zigzag curve after a promising start...

so can anyone check if my ideas are ok?

thanks
