Question

two bodies p and q are of mass m and 5m and velocity 5v and v compare their inertia , momentum and force required to stop

Answer 1

Answer:

momentum and force required to stop is mass ×velocity

5m×m,5m×v

Answer 2

Explanation:

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

(b) Momentum

P=m×v
