A nucleus of Uranium-238 (m = 3.95292599x10^-25 kg) ejects an alpha particle (m = 6.64465675x10^-27 kg), transmuting into a nucleus of Thorium-234 (m = 3.88638509x10^-25 kg).
If the alpha particle is ejected to the right at 1.443x10^7m/s, determine the magnitude of the velocity
of the nucleus as it recoils to the left.
V= ? •105 m/s to the left
