Question

Two balls A and B of masses 'm' and '2m' are in motion with velocities '2v' and '3v' respectively. After some time, their velocities changes to '4v' and '6v' respectively. 37.Compare the inertias of A and B.

Answer 1

Answer:

Hope the Answer help you

Explanation:

(i) Inertia depends on mass, and since the mass of the two balls are m and 2m, So the ratio of inertia of the balls 1:2

(ii)Momentum , p=mv

So, as per momentum equation, it depends on both mass and velocity.

So, their ratio =m×2v:2m×v=1:1
