Question

si unit of momentum2 balls a and b of masses m and 3m are in motion with velocities 3v and v respectively. their interia are in the ratio
​

Answer 1

Answer:

(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
