A 231 kg block is released at height h = 3.9 m. The track is frictionless except for a portion of length 6.6 m. The block travels down the track, hits a spring of force constant k = 1624 N/m, and compresses it 1.7 m from its equilibrium position before coming to rest momentarily.
The acceleration of gravity is 9.8 m/s^2.
Determine the coefficient of kinetic friction between surface and block over the 6.6 m track length.
