Question

In the figure, a runaway truck with failed brakes is moving downgrade at 110 km/h just before the driver steers the truck up a
frictionless emergency escape ramp with an inclination of 0 = 11°. The truck's mass is 1.1 × 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?
