A particle can slide along a track with elevated ends and a flat central part, as shown below. The flat part has length L = 40 cm. The curved portions of the track are frictionless, but for the flat part the coefficient of kinetic friction is µk = 0.34. The particle is released from rest at point A, which is a height h = L/2. How far from the left edge of the flat does the particle finally stop?
