Question

Two bodies P and Q of the same mass but are moving with the velocity 2V and 5v respectively find the ratio of their momentum

Answer 1

(i) Since the mass of the body is same therefore ratio of their inertia is 1:1

(ii) Momentum of body A = m (v)

Momentum of body B = m (2v) = 2mv

∴ Momentum of body A / Momentum of body B = mv/2mv

Or,

Momentum of body A: Momentum of body B = 1:2.

Hence,

→ its ratio is 1:2
