Suppose a 20,000 kg jet lands on the surface of an aircraft carrier. As it lands, it engages a tailhook wire, a wire which behaves as if it were connected to a spring with a spring constant of Ks = 25,000 J/m2. This slows the jet down to rest within 60 m. What was the jet's landing speed? (Actual tail hooks use hydraulics instead of a spring to absorb the just energy, but let's pretend).

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.
