QUESTION:
Suppose that 2 J of work is needed to stretch a spring from its natural length of 30 cm to a length of 42 cm.
(a) How much work is needed to stretch the spring from 35 cm to 40 cm?
(b) How far beyond its natural length will a force of 30 N keep the spring stretched?
ANSWER:Step 1 of 5
a)
Applying Hooke's law, the force required to keep a spring stretched units more than its natural length is proportional to
where is a positive constant (called the spring constant).
