Two dogs are playing in a park and they collide. The Great Dane has a momentum of 782 kg m/s, and poodle has a momentum of 18 kg m/s before the collision. If poodle has a momentum of 700 kg m/s after the collision, what is the momentum of the Great Dane?

Respuesta :

The total momentum is conserved.

Before the impact, the total momentum is

[tex]782+18=800\dfrac{\text{kg m}}{\text{s}}[/tex]

After the impact, the total must still be 800, so the Great Dane has a momentum of

[tex]800-700=100\dfrac{\text{kg m}}{\text{s}}[/tex]
