1. The problem statement, all variables and given/known data


Using the formula for kinetic energy of a moving particle K=1/2mv^2, find the kinetic energy K_a of particle a and the kinetic energy K_b of particle b.
Express your answers in terms of m,w ,r and separated by a comma.

2. Relevant equations



3. The attempt at a solution

I'm assuming w means 'omega' for angular velocity.

In that case, the equation v = rw will be very useful.
