37. A standing person pushes a nearby chair which then slides along the floor. The chair and person begin at rest and the person's feet remain at rest on the floor during the push. Compared to the magnitude of force that the person exerts on the chair, the magnitude of force that the chair exerts on the person a) is equal b) is smaller c) is larger d) the mass of the chair is needed to determine whether this force is larger, smaller, or equal e) the coefficient of kinetic friction is needed to determine whether this force is larger, smaller, or equal
