A 0.30-kg block slides along a small track with elevated curved ends and a flat central part. The flat part has a length L=144 m. The curved portions of the track have negligible friction, but the flat part of the track has a coefficient of kinetic friction of 0.186. The block is released from rest from a height h=62 cm on the left curved portion of the track. Calculate the maximum height reached by the block on the right curved portion of the track.
