A 0.80 kg block is placed on the track shown in the figure below. The left and right slopes of the track are frictionless, but there is friction between the block and the horizontal bottom part of the track. The block starts from rest at a vertical height h = 1.4 m on the left slope. The length of the horizontal bottom is L = 0.9 m, and the kinetic friction force has a constant magnitude of 0.5 N. What is the vertical height y where the block comes to a stop as it travels up the right slope? Give your answer in units of m.
