Question

A moving body of mass m1 collides another body of mass m2 After collision the velocity of first body becomes 2/3 of its intial value Then find theratio of m1 and m2

Answer 1

Explanation:

Using the Law of Conservation of Momentum,

Initial velocity = V

Final Velocity = 2V/3

M1 V = M2 ( 2V ) /3

M1 / M2 = 2 / 3

Therefore , the ratio M1 : M2 :: 2 : 3
