1) When you travel in the mountains, you will see \"Runaway Truck Ramps\" at many steep inclines. They are upward sloping ramps covered with loose gravel built to stop trucks whose brakes have failed. a) If the slope of the ramp is 6.00 degrees above the horizontal and the coefficient of kinetic friction is 0.400, how long does the ramp have to be to allow a 14,000 kg truck to stop when it enters the ramp at 120 km/hr? Solve this problem using work by the nonconservative forces acting WNC and mechanical energy E: WNc = Ef - E where E = K + U
