57. A 190-g block is launched by compressing a spring of constant
k = = 200 N/m by 15 cm. The spring is mounted horizontally,
and the surface directly under it is frictionless. But beyond the
equilibrium position of the spring end, the surface has frictional
coefficient μ = 0.27. This frictional surface extends 85 cm, fol-
lowed by a frictionless curved rise, as shown in Fig. 7.21. After
it's launched, where does the block finally come to rest? Measure
from the left end of the frictional zone.
