From a stationary tank of mass 125000 pound a small shell of mass 25 pound is fired with a muzzle velocity of 1000 ft/sec. The tank recoils with a velocity of
Text Solution
Verified by ExpertsThe correct answer is:
B
According to conservation of momentum
Momentum of tank = Momentum of shell
125000 × v tank = 25 × 1000 ⇒ ⇒ v tank = 0.2 ft/sec.
