a 100 kg cart moving at 15 m/s collides with a 50 kg cart at rest, causing both carts to move together in the same direction. If momentum is conserved at what speed are the two carts now moving?

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
