A body of mass 0.25 kg is projected with muzzle velocity 100 m/s from a tank of mass 100 kg. What is the recoil velocity of the tank?

Question

A body of mass 0.25 kg is projected with muzzle velocity 100 m/s from a tank of mass 100 kg. What is the recoil velocity of the tank? (A) 5 m/s (B) 25 m/s (C) 0.5 m/s (D) 0.25 m/s

Using law of conservation of momentum, we get 100 × v =0.25 × 100 v =0.25 m / s

Q. A body of mass $0.25 k g$ is projected with muzzle velocity $100 m / s$ from a tank of mass $100 k g$ . What is the recoil velocity of the tank?

5 m/s

25 m/s

0.5 m/s

0.25 m/s

Using law of conservation of momentum, we get
$100 \times v = 0.25 \times 100$
$v = 0.25 m / s$
