A 60.0-kg skier with an initial speed of 12.0 m/s coasts
Chapter 7, Problem 24(choose chapter or problem)
A \(\text { 60.0-kg }\) skier with an initial speed of \(12.0 \mathrm{~m} / \mathrm{s}\) coasts up a \(2.50-\mathrm{m}\) high rise as shown in Figure \(7.40\). Find her final speed at the top, 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.)
Figure \(7.40\) The skier’s initial kinetic energy is partially used in coasting to the top of a rise.
