You push a file cabinet up a rough ramp tilted at 10.0° with horizontal at a constant speed of 1.50 m/s. The file cabinet has a mass of 30.0 kg and you are pushing with a 150 N force in the direction up along the ramp. It’s moved 4.20 m up along the ramp. Use g = 10.0 m/s2. Assuming the system is cabinet+earth+ramp, match the answers with questions. ΔK + ΔUg + ΔUsp + ΔEth + ΔEch = Wexternal

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?”
