A nucleus A of mass 2 m moving with velocity u collides inelastically with a stationary nucleus B of mass 10 m. After collision the nucleus A travels at 90 with the incident direction while B proceeds at an angle 37 with the incident direction. (a) Find the speeds of A and B after the collision. (b) What fraction of the initial kinetic energy is gained or lost due to the collision.

Solution:
A nucleus A of mass 2 m moving with velocity u collides inelastically with a sta
