## Homework Statement

Two coordinate systems

**xyz**( fixed) and

**x0y0z0**(moving) coincide at time t = 0.

The moving system is rotating about the fixed

**z**axis, which coincides with z0 axis. The angular velocity is given by

**ω**= t

**k**= t

**k0**. The position vector as measured in the rotational frame is equal to

**r0**(t) = (t + 1)

**i0**+ t^2

**j0**:

1. Using the rotating frame find

**v0**.

## Homework Equations

**ω**= t

**k**= t

**k0**

**r0**(t) = (t + 1)

**i0**+ t^2

**j0**

## The Attempt at a Solution

So i know to find

**v0**, i cannot just differentiate

**r0**. but i am stuck.
