A 10 kg monkey climbsup a massless rope that runs over africtionless tree limb and backdown to a 15 kg package on theground . (a) What is themagnitude of the least accelerationthe monkey must have if it is to liftthe package off the ground? If, afterthe package has been lifted, themonkey stops its climb and holdsonto the rope, what are the (b)magnitude and (c) direction of themonkey’s acceleration and (d) thetension in the rope?

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?”
