(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A stationary uranium-238 nucleus undergoes alpha-decay. What is the ratio of the daughter nucleus to that of the alpha-particle?

P.S. It's a practice problem for which I had the final answer, but I'm not sure how to reach it.

2. Relevant equations

I guess it's based on conservation of energy. I'm unsure of the equations, though.

1/2 mv^2 for K.E.

3. The attempt at a solution

Sorry, I just don't know how to start.
