A 0.40-kg block slides along a small track with elevated ends and a flat central part. The flat part has a length L = 1.84 m. The curved portions of the track are frictionless, but for the flat part the coefficient of kinetic friction is 0.132. The block is released from rest from a height h = 51 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.
