Newton's second law of motion:

                       Force  =  (mass)  x  (acceleration)

                                   =  (100 kg)  x  (-5 m/s²)

                                   =          -500 Newtons .

I made the acceleration negative because the cart is slowing down.
The force came out negative because it's in the direction opposite
to the cart's motion.
