    Answer:

    d. – 2.50 N

    Explanation:

    – 2.50 N is the net force that Marisa applied on the sled. Marisa applied force in order to stop the sled and requires less amount of force due to its lower mass. The value of force is negative because the force is applied in opposite direction of the sled’s movement. The value of force is positive when it is applied in the direction of the object’s motion so the value of force is – 2.50 N which is applied in opposite direction of the body’s motion.
