Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”

Question

A Shopee delivery man named lan is dragging a trunk up the loading ramp of the
delivery truck. The ramp has a slope angle of 20.0°, and lan pulls upward with a force
(F) whose direction makes an angle of 30.0° with the ramp.
a.) How large a force (F) is necessary for the component Fx parallel to the ramp be 75.ON?
b.) How large will the component Fy perpendicular to the ramp be?
