In the figure, a runaway truck with failed brakes is moving downgrade at 147 km/h just before the driver steers the truck up a frictionless emergency escape ramp with an inclination of θ = 12°. The truck's mass is 1.0 × 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 truck’s mass is decreased and (c) its speed is decreased?
Hope this helps.
Please rate positively.

A truck with failed brakes is moving downgrade at 120 km/hr just before the driver steers the truck up an emergency escape ramp with an inclination of theta= 15 degrees. The trucks mass is 1.4x10^4 kg. Assume that the rolling friction behaves like kinetic friction, and the coefficient of rolling friction between the tires and ramp is 0.10. What minimum length L must the ramp have if the truck is to stop (momentarily) along it?
