Answer

The momentum of the plastic cart is equal to the momentum of the lead cart after the force is removed.

Work Step by Step

The same force is used on each cart for the same amount of time. Therefore the impulse on each cart is equal. Therefore the change in momentum of each cart is equal. Since both carts started from rest, the momentum of the plastic cart is equal to the momentum of the lead cart after the force is removed.
