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.

You are the physics consultant working on an action movie set where an SUV must start from rest, accelerate along a pier, and jump over a stretch of water to land in a departing ferry. (The director assures you it will all be very exciting.) The drawing below shows the situation. The SUV has four-wheel drive (see problem N5D.1), and the coefficients of friction between the tires and the pier’s surface are us =3/4 and uk = 1/2. Calculate the length L (as a fraction or multiple of D) of the run along the pier that you will need for the SUV to make it to the ferry. Ignore air drag.
