Answer :
Final answer:
The recoil velocity of the rifle is approximately 300m/s.
Explanation:
In physics, the law of conservation of momentum states that the total momentum of a system remains constant if no external forces act upon it. In this case, the recoil of a rifle is an example of this law. Initially, the total momentum is zero as both the rifle and bullet are stationary. After the bullet is fired, it has momentum, but to keep total momentum constant, the rifle must gain a negative momentum. This is seen as the rifle moving backwards, also called recoil.
The momentum of the bullet and the recoil of the rifle can be calculated using the formula m1v1=m2v2 where m1 is the mass of the bullet, v1 is the velocity of the bullet, m2 is the mass of the rifle, and v2 is the recoil velocity of the rifle. Plugging in the given values, the recoil velocity comes out to be -60 m/s (negative indicating it moves in opposite direction to the bullet).
