"An Astatine 219 nucleus and an alpha particle at a spacing of 1.5 x 10^-15 m are formed during alpha decay. If the initial velocity of the two particles is zero, calculate the ratio of their velocities."

I was thinking of making a ratio of their kinetic energy, but I'm not sure if that's simplifying the problem too much.

If I make a ratio, I get:

.5 x m1 x v1^2 : .5 x m2 x v2^2

...

v1

--- = sqrt [m2 / m1]

v2

Is this right?
