Bored, a boy shoots his pellet gun at a piece of cheese which sits, keeping cool for dinner guests, on a massive block of ice. On one certain shot, his 1.3 g pellet gets stuck in the cheese, causing it to slide 25 cm prior to coming to a stop. When the muzzle velocity of the gun is 56 m/s and the cheese consists of a mass of 115 g, determine the coefficient of friction between the ice and cheese?
