as You may have noticed runaway truck lanes while driving in the mountains. These gravellled lanes are designed to stop trucks that have lost their brakes on mountain grades. Typically, such a lane is horizontal (if possible) and about 39.0 m long. Think of the ground as exerting a frictional drag force on the truck. A truck enters a typical runaway lane with a speed of 57.0 mph [25.5 nus). Use the workenergy theorem to nd the minimum coefcient of kinetic friction between the truck and the lane to be able to stop the truck. ii: Macmillan Learnin pk: A small boat is crossing a lake on a windy day.
