a sled with a boy on it has a combined mass of m = 75 kg. as they slide across a horizontal surface of an ice-
covered lake, they come to rest in a distance of s = 25 m. if the coefficient of friction between the sled and the ice
is u = 0.25, calculate the amount of work done on the sled by friction. keep in mind - negative work decreases
kinetic energy whereas positive work increases it. so, don't forget a negative sign in front of your answer.
