A $58\mathrm{.}0$ kg skier with an initial speed of $v_i=14\mathrm{.}5\frac{m}{s}$ coasts up a $h=2\mathrm{.}10m$ high rise as shown in the figure below. Find her final speed at the top, given that the coefficient of friction between her skis and the snow is $0\mathrm{.}0840$ and the angle $=31\mathrm{.}0.($Hint: Find the distance traveled up the incline assuming a straight$-$line path as shown in the figure.$)$

Friction is a

nonconservative force because it removes mechanical energy from

$$ the system.

Correct answer, well done.
