## Homework Statement

A body, initially at rest, explodes into two pieces of mass 2M and 3M respectively, having a total kinetic energy E.

What is the kinetic energy of the piece of mass 2M after the explosion?

## Homework Equations

0.5mv²=K.E

## The Attempt at a Solution

The velocity of the 2 pieces of objects is different,how do i calculate?

Can anyone guide me on how to start?

0.5(2m)(v_1)² + 0.5(3m)(v_2)²=E

How do i proceed?

Thanks for reading,thinking,replying.
