Willie’s class found that the cart will move when pushed with 50 Newton’s of force. When Willie pushes on the cart with 10 Newton’s of force, why didn’t the cart move?

The cart does not move because it is applying the same force as Willie is applying to it. When he pushes with 50 N (Newtons) of force his force is greater than the cart's. When he pushes the cart with 10 N, the force he is applying and the cart is applying is equal.
