Using the formula for kinetic energy of a moving particle k=12mv2, find the kinetic energy ka of particle a and the kinetic energy kb of particle b. remember that both particles rotate about the y axis. express your answers in terms of m, ω, and r separated by a comma.

Complete Question

The complete question is shown on the first uploaded image

The kinetic energy for particle a is  

The kinetic energy for particle b is  

Explanation:

From the question we are told that

   The mass of particle a  is    

   The mass of particle b is    

Generally the kinetic energy for  particle a is mathematically represented as  

Here is the linear velocity of particle a which is mathematically represented as

So

=>
