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

A

0.1 ft/ sec

B

0.2 ft/sec

C

0.4 ft/sec

D

0.8 ft/sec

Text Solution

Verified by Experts

The correct Answer is:
B
According to conservation of momentum
Momentum of tank = Momentum of shell
`125000xx v_("tank")=25xx1000 rArr v_("tank") 0.2` ft/sec.
