A sledge loaded with bricks has a total mass of 18.7 kg and is pulled at constant speed by a rope inclined at 19.5° above the horizontal. The sledge moves a distance of 19.4 m on a horizontal surface. The coefficient of kinetic friction between the sledge and surface is 0.500. Find parts a-c.
You may have noticed runaway truck lanes while driving in the mountains. These gravel-filled lanes are designed to stop trucks that have lost their brakes on mountain grades. Typically, such a lane is horizontal (if possible) and about 40.0 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 50.5 mph (22.6 m/s). Use the work-energy theorem to find the minimum coefficient of kinetic friction between the truck and the lane to be able to stop the truck.

Using the work-energy theorem to investigate a traffic scene A car hit a pedestrian and immediately the driver slammed on the brakes to stop the car. During the subsequent trial, the driver's lawyer claimed his client was obeying the posted 35-mi/hr speed limit. You have been called in as the state's expert witness. Your investigation of the accident found that the skid marks made while the brakes were applied until the car stopped were Ax = 94 m long. You also measured the coefficient of kinetic friction between the car's tires and the road (using a drag sled) to be μk = 0.36. (a) Use the work-energy theorem to show that the car's minimum speed vo when the driver slammed on the brakes is given by vo = √2 μg Ax (b) Use the result of part (a) to determine if the car was speeding when the pedestrian was hit. [answer: The car's speed was at least 57 mi/hr when the brakes were applied.] (c) If the car's mass is 1470 kg, how much heat energy was produced while the car was skidding? [answer:…

You may have noticed runaway truck lanes while driving in the mountains. These gravel-filled lanes are designed to stop trucks that have lost their brakes on mountain grades. Typically, such a lane is horizontal (if possible) and about 35.0 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 55.5 mph (24.8 m/s). Use the work-energy theorem to find the minimum coefficient of kinetic friction between the truck and the lane to be able to stop the truck.
