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.

Shrinking Loop. A circular loop of flexible iron wire has an initial circumference of 161 cm , but its circumference is decreasing at a constant rate of 15.0 cm/s due to a tangential pull on the wire. The loop is in a constant uniform magnetic field of magnitude 1.00 T , which is oriented perpendicular to the plane of the loop. Assume that you are facing the loop and that the magnetic field points into the loop. Find the magnitude of the emf E induced in the loop after exactly time 9.00 s has passed since the circumference of the loop started to decrease. please show all steps
