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.

The diagram shows the all of the forces acting on a body of mass 3.13 kg. The three forces have magnitudes F1 = 59.2 N, F2 = 27.7 N, and F3 = 74.4 N, with directions as indicted in the diagram, where θ = 55.8 degrees and φ = 21.4 degrees.

A light plane of mass 1000kg makes an emergency landing on a short runway. With its engine off, it lands on the runway at a speed of 40m⋅s-1 . A hook on the plane snags a cable attached to a 120kg sandbag and drags the sandbag along. If the coefficient of friction between the sandbag and the runway is µk = 0.4, and if the plane’s brakes give an additional retarding force of magnitude 1400N, how far does the plane go before it comes to a stop?
