A 209 kg block is released at height h =
3.3 m as shown. The track is frictionless
except for a portion of length 7 m. The block
travels down the track, hits a spring of force
constant k = 1545 N/m, and compresses it
1.9 m from its equilibrium position before
coming to rest momentarily.
The acceleration of gravity is 9.8 m/s
Determine the coefficient of kinetic friction
between surface and block over the 7 m track
length.
