A uranium-238 nucleus, initially at rest, emits an alpha particle with a speed of 1.4 x 10^7 m/s. Calculate the recoil speed of the residual nucleus thorium-234. Assume that the mass of a nucleus is proportional to the mass number.

Thanks for asking the question!
ANSWER::
Given - Uranium-238 nucleus emits α-particle with speed of 1.4 x 10⁷ m/s.
Let v₂ be the speed of residual nucleus thorium-234
Therefore,
m₁v₁=m₂v₂
4 x 1.4 x 10⁷ = 234 x v₂
v₂ = (4 x 1.4 x 10⁷) / 234
v₂ = 2.4 x 10⁵ m/s
Hope it helps!
