Question

A rifle with a mass of m1 = 3.4 kg fires a bullet with a mass of 8.3 g (0.0083 kg). The bullet moves with a velocity of 860 m/s after the rifle is fired. What is the momentum of the bullet after the rifle is fired?

Answer 1

P = 7.138 kg m/s

Step-by-step explanation:

As we know that momentum is the product of mass and velocity

So here we have

m = 0.0083 kg

velocity = 860 m/s

so momentum of the bullet is given as

`P = mv`

`P = (0.0083)(860)`

`P = 7.138 kg m/s`

so the momentum of bullet after it has been shoot from the rifle is given as

P = 7.138 kg m/s
