b) Use the work-energy theorem to calculate the velocity. 5. A truck traveling down the mountain loses its brakes. Fortunately, just ahead is a runaway truck ramp, which slopes uphill at an angle of 30 degrees from horizontal. The truck has a mass of 10,000 kg and is moving at a speed of 100 km/hr just before starting up the ramp. The ramp is covered with gravel to provide a lot of friction, giving an effective coefficient of kinetic friction ux = 0.70. Using the work-energy theorem, calculate how far up the ramp the truck goes before stopping. Give the distance along the ramp, not the vertical rise.

5. A truck traveling down the mountain loses its brakes. Fortunately, just ahead is a runaway
truck ramp, which slopes uphill at an angle of 30 degrees from horizontal. The truck has a
mass of 10,000 kg and is moving at a speed of 100 km/hr just before starting up the ramp.
The ramp is covered with gravel to provide a lot of friction, giving an effective coefficient of
kinetic friction =0.70. Using the work-energy theorem, calculate how far up the ramp the
truck goes before stopping. Give the distance along the ramp, not the vertical rise.
