Suppose that 4 J of work is needed to stretch a spring
from its natural length of 28 cm to a length
of 43 cm.
(a)
How much work (in J) is needed to stretch the spring
from 36 cm to 38 cm? (Round your answer to
two decimal places.)
J
(b)
How far beyond its natural length (in cm) will a force
of 15 N keep the spring stretched? (Round your answer one
decimal place.)
