A sled of 150 kg mass moves along a smooth horizontal surface at 7 m/S The sled encounters a rough spot that exerts a force of -90 Nt on the sled. (a) What is the acceleration of the sled? (b) Calculate how much work is done by the frictional force on the sled if the patch is 15 m in length. (c) What is the sled's final velocity as it leaves the rough spot?
