Cart A (200 g) is moving to the left at 1.0 m/s
and Cart B (200 g) is moving to the right at 1.0
m/s. Cart A is attached to a rubber band that
exerts an impulse of 0.1 N-s then snaps. Cart B
has clay on it, so the two carts will stick
together after they collide.
What will be the combined carts' new speed?
In which direction?
