A light plastic cart and a heavy metal cart are both free to roll having negligible friction on a horizontal surface. Each cart begins from rest. A force is exerted to each and every cart to push it forward, and the force is eliminated when the cart has traveled 1 meter. The forces on each and every cart are of equivalent magnitude.
i) Which cart consists of the larger final momentum? Describe.
ii) When the force on each cart is eliminated after 1 second instead of after 1 meter, which cart consists of the larger final kinetic energy? Describe.
