Question

Two bodies A and B having masses in the ratio of 3 : 1 possess the same kinetic energies. The ratio of linear momenta of B to A is, 1 : 3, 3 : 1, 1 : 3, 3 : 1

MARKS App · Accepted Answer

As 1 2 m A v A 2 = 1 2 m B v B 2 v A v B = m B m A ; P B P A = m B v B m A v A = m B m A m A m B = m B m A = 1 3
