Two point-particles having masses m1 and m2 approach each other along mutually perpendicular directions with speeds v1 and v2, respectively. After a perfectly elastic collision, they move away from each other along mutually perpendicular directions with speeds v′1 and v′2, respectively. Assuming the final velocity vectors are also perpendicular to each other, the ratio v′2v′1 is given by:
