Concept explainers

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.
Question
A 60.0 kg skier with an initial speed of 10.0 m/s coasts up a 2.50 m high rise as shown in the following figure. V = ? KE, 2.5 m 35° Find her final speed at the top (in m/s), given that the coefficient of friction between her skis and the snow is 0.0800. (Hint: Find the distance traveled up the incline assuming a straight-line path as shown in the figure.) m/s
