A uraniun-238 ,initially at rest ,Emits an alpha particle with a speed of 1.4*10⁷.calculate the recoil speed of the residual nucleus thorium-234. assume that the mass of a nucleus is proportional to the mass number

Use conservation of momentum

k x 4 x 1.4 x 10⁷ = k x 234 x v (assuming no external force acts on the system)

(we use k as the absolute mass is proportional to the mass number)

hence find v
