Question

Two bodies A and B are of mass M and 4M respectively and their velocities
are 4v and v respectively. Compare their inertia and force required to stop
them​

Answer 1

Answer:

(a) Since inertia is a measure of mass which is same for both bodies, so the ratio of inertia for two bodies will be
