Homework Help: Physics

Posted by Laura Khoshaba (Me and I) on Monday, February 3, 2014 at 3:46pm.

I think I chose the correct answer.

In a closed system, two carts have a compressed spring between them. One of the carts has a total mass, including its contents, of 2.0 kg, and the other has total mass of 1.0 kg. Which cart experiences the momentum change of greater magnitude after the spring is released to push them apart?

The 1.0 kg cart has the greatest change in momentum.

The 2.0 kg cart has the greatest change in momentum.

Each has a momentum change of the same nonzero magnitude. <------

Each has zero momentum change.
