An out-of-control truck with a mass of 5000 kg is traveling at 35.0 m/s (about 80 mi/h) when it starts descending a steep (15°) incline. The incline is icy, so the coefficient of friction is only 0.30. Use the work-energy theorem to determine how far the truck will skid (assuming it locks its brakes and skids the whole way) before it comes to rest.
