Lwt atoms of nucleus with mass no. m
And alpha partivle has mass 4
Hence
(Atoms molecule)m = (alpha)⁴ + (daughter mass)m-4
 
 
Initial mass = m
Injtial velocity = 0
Initial momentum = 0
Final mass = m & m-4
Final velocity of alpha is v and daughter is v'
 
0 = 4v + (m-4) v'
V' = -4v/(m-4)
Negative sign indicated the opposite direction
