What is the momentum of a two-particle system composed of a 1400 kg car moving east at 70 m/s and a second 1300 kg car moving west at 85 m/s? Let east be the positive direction and answer to 3 significant figures.

Respuesta :

Answer:

209000 kg*m/s

Explanation:

Momentum is caclucated using the equation P=mv. Where m is mass and v is velocity.

If you are required to show your work it would be the following:

1400*70=98000 kg*m/s

1300*85=110500 kg*m/s

98000+110500=208500 kg*m/s

209000 kg*m/s
