A 10-kilogram block is dropped from point A as shown. The rail is frictionless except for the 6 m long B and C parts. The block slides down the rail and hits a pedestrian with k = 2250 N / m and stops for a moment by compressing the spring by 30 cm according to the balance position. Find the kinetic friction coefficient between the B and C part of the rail and the block
