Homework Statement
An explosive of mass M is initially at rest. It then explodes into two pieces and travels along a straight line. The small piece has mass M1, speed V1, and kinetic energy K1=(1/2)M1V12. The kinetic energy of the bigger mass would be in terms of K1 would be:
Homework Equations
K=(1/2)mv2
The Attempt at a Solution
I'm not sure how to proceed without a mass ratio. The answer is [M1/(M-M1)]K1
