A truck (m = 10000 kg) is traveling at a speed of 30 m/s (about 70 mph) down the Kailua side of the Pali Highway when its brakes cut out. The truck driver quickly navigates to a "runaway truck ramp" to slow down enough that he can apply his emergency brakes. If the truck was originally at a height of 10.0m above the bottom of the "runaway truck ramp", and friction is negligible, how high up the ramp (height) does the truck need to go to come to a stop?

Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.
