## Homework Statement

So I have to prove that the total velocity of a particle on a wheel is Vcm+Ui=Vi where Ui is the particles velocity if the wheel's center of mass wasn't moving so just v=omega*R I'm assuming and Vcm is the velocity of the center of mass and Vi is the total velocity of the point on the wheel.

## Homework Equations

a^2+b^2=c^2

## The Attempt at a Solution

You can draw a diagram of the before and after of the particle after time t. You can then place the x and y components for the Ui and Vcm head to tail and you can get the (Uix+Vcm)^2+(Uiy)^2 = Vi^2 (Vcm only has an x component) but I don't know how to get from this to Vcm+Ui=Vi
