<p>A particle slides along a track with elevanted ends a flat central part as shown in the figure. The flat part has a length l = 3m. The curved portions of the track are frictionaless. For the flat part the coefficient of kinetic friction is&nbsp;<math xmlns="http://www.w3.org/1998/Math/MathML"><msub><mi>&#956;</mi><mi>k</mi></msub></math>&nbsp;= 0.2. The particle is released at point A which is at height h = 1.5m ab ove the flat part of the track. Where does the particle finally come to rest?</p>
