Answer 1

Explanation:

this is the answer for your question

Answer 2

Answer:

Recoil is the backward momentum of a gun when it is discharged . Recoil velocity of a gun is the velocity by which the gun recoils after being shot . According to Newton's third law of motion -every action has an equal and opposite reaction. 

Explanation:

It's now easy to calculate the recoil speed of the rifle (vR)in feet/second: vR = -(mB ÷ mR) vB = -(9.72 g ÷ 3,632g) 2,820 ft/s = -7.55 ft/s. The minus sign denotes the fact that recoil speed is in the opposite direction to the speed of the bullet.A recoil is a movement backwards, usually from some force or impact. The recoil of a gun is a backward movement caused by momentum. Your trip to the shooting range might make your mom recoil — from horror, not momentum. Recoil has both a verb and a noun form, meaning any kind of rebound or spring backwards.
