A runaway truck with failed brakes is moving downgrade at 146 km/h just before the driver steers, the truck travels up a frictionless emergency escape ramp with an inclination of 15°. The truck's mass is 5000 kg.(adsbygoogle = window.adsbygoogle || []).push({});

(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 justufy that assumption.)

I know that the minimum length stays the same if the truck's mass is decreased. and the minimum length decreases if the truck's speed is decreased.

I am clueless on what equation to use to find the minimum length L. Can someone please help me out.
