Question

two
balls of equal masses m each undergo oblique collision. If collision is perfectly elastic, then angle between their
velocities after collision is
​

Answer 1

Answer:

The degree to which a collision is elastic or inelastic is quantified by the coefficient of restitution, a value that generally ranges between zero and one. A perfectly elastic collision has a coefficient of restitution of one; a perfectly-inelastic collision has a coefficient of restitution of zero.
