Collision Of Particles Part 2

A particle A suffers an oblique elastic collision particle B that is at rest initially. If their masses with a are the same, then after the collision

Particle 1 experiences a perfectly elastic collision with a stationary particle 2. Determine their mass ratio, if (a) after a head-on collision the particles fly apart in the opposite directions with equal velocities, (b) the particles fly apart symmetrically relative to the initial motion direction of particle I with the angle of divergence theta=60^@ .

In one dimeensional collision of two particles velocities are interchanged when (a)Collision is elastic and masses are equal (b)Collision is inelastic but masses are unequal

Consider elastic collision of a particle of mass m moving with a velocity u with another particle of the same mass at rest. After the collision the projectile and the struck particle move in direction making angles theta_(1) and theta_(2) respectively with the initial direction of motion. The sum of the angles. theta_(1)+theta_(2) , is

Conservation of momentum in a collision beween particles can be understood form
