2A particle can slide along a track with elevated ends and a flat central part, as shown in Fig. 8-86. The flat part has length \( L=40 \mathrm{~cm} \). The curved portions of the track are frictionless, but for the flat part the coefficient of kinetic friction is \( \mu_{k}=0.20 \). The particle is released from rest at point \( A \), which is at height \( h=L / 2 \). How far from the left edge of the flat part does the particle finally stop?
