A boy shoots his pellet gun at a piece of cheese that sits, keeping cool for dinner guests, on a massive block of ice. On one particular shot, his .01 kg pellet gets stuck in the cheese, causing it to slide 1 meter before coming to a stop. If the muzzle velocity of the gun is 64 m/s and the cheese has a mass of .2 kg, what is the coefficient of friction between the cheese and the ice?

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?”
