Given : a bullet of mass 30g is fired from a gun of mass 9kg. the velocity of the bullet is 400m/s,
To Find: the recoil velocity of the gun will be
Solution:
Recoil velocity is the backward velocity experienced by a shooter when shoots a bullet.
Initial velocity of gun and bullet = 0
u₁ and v₁ are = 0
u₁ = Initial velocity of gun = 0
u₂ = Initial velocity of bullet = 0
mass of gun = m₁ = 9 kg = 9000 g
mass of bullet = m₂ = 30 g
v₁ = Recoil velocity of gun ( back ward velocity )
v₂ = velocity of bullet = 400m/s
Conservation of momentum :
m₁u₁ + m₂u₂ = m₁(-v₁) + m₂v₂
( note v₁ is taken as -ve because v₁ is recoil velocity hence backward )
=> 9000 * 0 + 30*0 = 9000(-v₁) + 30(400)
=> v₁ = 1.33
Hence 1.33m/s in the opposite direction of the bullet
