Question

a bullet of mass 10g is fired from mass 6kg with a velocity of 250 m/s .calculate the recoil velocity of gun​

Answer 1

Answer:

Mass of bullet, m = 10 g = 0.01 kg Mass of Gun, M = 5.0 kg Velocity of bullet, v = 250 m/s Let the velocity with which Gun recoils is V. By the law of conservation of momentum, Initial momentum of the system = Final momentum of the system. m(0) + M(0) = mv + V V=- 0.01 x 250/5.0= -0.5m/s Recoil velocity of the gun is 0.5

Answer 2

Answer:

Mass of bullet, m = 10 g = 0.01 kg

Mass of Gun, M = 5.0 kg

Velocity of bullet, v = 250 m/s

Let the velocity with which Gun recoils is V.

By the law of conservation of momentum, Initial momentum of the system = Final momentum of the system.

m(0) + M(0)

= mv + V V

=- 0.01 x 250/5.0

= -0.5m/s

Recoil velocity of the gun is 0.5 m/s.
