Learning Goal:

To practice Problem$-$Solving Strategy $10\mathrm{.}1$ for energy conservation problems.

A sled is being held at rest on a slope that makes an angle $\backslash (\backslash$theta $\backslash )$ with the horizontal. After the sied is released, it sides a distance $\backslash ($ d$\_\{1\}\backslash )$ down the slope and then covers the distance $\backslash ($ d$\_\{2\}\backslash )$ along the horizonta terrain before stopping. Find the coefticient of kinetic friction $\backslash (/4\backslash )$ between the sled and the ground. assuming that it is constant throughout the trip.

A complete pictorial representation of this problem should incude a before$-$and$-$after pictorial representalion like this one:

Solve

Part B

Find the coefficient of kinetic friction $\backslash (\backslash$mu$\_\{$k$\}\backslash ).$

Express your answer in terms of some or all of the variables $\backslash ($ d$\_\{1\},$ d$\_\{2\}\backslash ),$ and $\backslash (\backslash$theta $\backslash ).$
