Physics Particle Decay Question (Cons. of Momentum??)
An isotope of Polonium 210Po with mass 3.49x10^-25 kg can decay into an alpha-particle(He Nucleus) with mass of 6.64x10^-27 kg and an isotope of lead 206Pb with a mass of 3.42x10^-25. If the polonium decays at rest. and the final decay products have a total KE of 8.65x10^-13 J, what are the speeds of the He and Pb nuclei?
(m1+m2)Vo = m1v1 + m2v2
My first thought was to plug in what was given but then I get stuck...
(Po)(0) = (He)(V_He) + (Pb)(V_Pb)
That gets me nowhere.
It's multiple choice
A. 0.17 m
B. 0.15 m
C. 0.08 m
D. 0.03 m
E. 0.00 m
I wish I could show more work, I just don't know where to go with it at all
