nfortunate small car crashes against a large moving truck. Compared to the force of the small car on the large truck, what is the force of the large truck on the small car?

As shown in the figure, a woman is straining to lift a large crate, but without success because it is too heavy. We denote the forces on the crate as follows: P is the magnitude of the upward force being exerted on the crate by the person, C is the magnitude of the vertical contact force on the crate by the floor, and W is the weight of the crate. How are the magnitudes of these forces related while the person is trying unsuccessfully to lift the crate? OA P=C OB.P+C>W OCP+C
