Momentum and CollisionHard
Question
A gun fires a bullet of mass 50 g with a velocity of 30m/s. Due to this, the gun is pushed back with a velocity of 1m/s, them the mass of the gun is :
Options
A.1.5kg
B.5.5kg
C.0.5kg
D.3.5kg
Solution
Applying conservation of momentum MV = mv
M ×1 =
×30 = 
M = 1.5kg
M ×1 =
×30 = M = 1.5kg
