A bullet of 10g leaves a 20kg gun with a velocity 100m/s. find the velocity of recoil of the gun.
Answers
Given : From a rifle of mass 20kg, a bullet of mass 10g is fired with an initial velocity of 100m/s.
To Find : What is the initial velocity of recoil of the rifle ?
Solution:
Apply conservation of momentum
initial Momentum = (20kg + 10g) * 0 = 0 kgm/s
, a bullet of mass 10g is fired with an initial velocity of 100m/s.
=> mv = (10/1000) 100 = 1 kgm/s
a rifle of mass 20kg initial velocity of recoil of the rifle = v
=> -20v ( as recoil velocity is backward velocity hence -ve sign will be there)
0 = 1 - 20v
=> 20v = 1
=> v = 1/20 m/s
=> v = 0.05 m/s
the initial velocity of recoil of the rifle = 0.05 m/s
