Answer

No, hanging a magnet on the front of the cart will not make it go.

Work Step by Step

No, hanging a magnet on the front of the cart will not make it go. According to Newton's third law, whatever force the magnet exerts on the cart, the cart exerts an equal and opposite force on the magnet. Then the net force on the cart-magnet system is zero. Therefore, the cart-magnet system will not start moving.
