In Fig. 8-35, a runaway truck with failed brakes is moving downgrade at 130 km/h just before the driver steers the truck up a frictionless emergency escape ramp with an inclination of u 15.The trucks mass is 1.2 104 kg. (a) What minimum length L must the ramp have if the truck is to stop (momentarily) along it? (Assume the truck is a particle, and justify that assumption.)Does the minimum length L increase, decrease, or remain the same if (b) the trucks mass is decreased and (c) its speed is decreased?
