Given:
A bullet of mass 10 g is fired horizontally with a velocity of 150 ms-1 from a gun of mass 4 kg.
To find:
Recoil Velocity
Calculation:
Let recoil Velocity be v ;
Applying Conservation of Momentum;
Negative recoil velocity shows the fact that the gun recoils in the opposite direction as compared to that of the movement of the bullet.
So, final answer is:
Question:-
A bullet of mass 10 g is fired horizontally with a velocity of 150 ms-1 from a gun of mass 4 kg. calculate the recoil velocity of gun.
Answer:-
Given:
Applying law of conservation of momentum:-
=> (4 * v) + (0.01 * 150) = (4 * 0) + (0.01 * 0)
=> v = (-15)/4 m/s
=> v = -3.75 m/s
-ve sign indicates that the gun moves in backward direction
Ans. Recoil Velocity = -3.75 m/s
