(f) Find the potential energy stored in the spring when x = 0.160 m.
(g) Suppose the same system is released from rest at x = 0.215 m on a rough surface so that it loses 15.2 J by the time it reaches its first turning point (after passing equilibrium at x =
0).
What is its position at that instant?
m
