Math Problem Statement
A 180 g block is launched by compressing a spring of constant k= 200N/m a distance of 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 coefficient of friction μ=0.27 . This frictional surface extends 85 cm , 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.
