A 189g block is launched by compressing a spring of constant k= 200 N/m a distance of 15cm . 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 coefficient of friction 0.27. This frictional surface extends 85cm , followed by a frictionless curved rise, as shown in the figure. After launch, where does the block finally come to rest? Measure from the left end of the frictional zone.
