Question

Find the momentum of a 0.0231 kg bullet fired at 621 m/s.*

A.0.0269 kg·m/s
B.14,200 kg·m/s
C.26.9 kg·m/s
D. 14.3 kg·m/s​

Answer 1

The momentum of a 0.0231 kg bullet fired at 621 m/s is calculated by multiplying the mass of the bullet by its velocity:0.0231 kg * 621 m/s = 14.3 kg·m/sSo the answer is D. 14.3 kg·m/s.

Step-by-step explanation:

Answer 2

Formula for momentum:

`p=mv`

momentum(measured in kg*m/s) = mass(measured in kg) * velocity(measured in m/s)

__________________________________________________________

Given:

`m=0.0231kg`

`v=621m/s`

`p=?`

__________________________________________________________

Finding momentum:

`p=mv`

`p=0.0231*621`

`p=14.3kg*m/s`
