Atruck traveling down the mountain loses its brakes. fortunately, just ahead is a runaway truck ramp, which slopes uphill at an angle of 35 degrees from horizontal. the truck has a mass of 9000 kg and is moving at a speed of 110 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 ൌ 0.60. 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.
