Suppose that 2 Joules of work is needed to stretch a spring from
its natural length of 40 cm to a length of 61 cm. How much work is
needed to stretch it from 54 cm to 65 cm? Your answer must include
the correct units.

A spring has a natural length of 30 cm. If a 20-N force is
required to keep it stretched to a length of 46 cm, how much work
W is required to stretch it from 30 cm to 38 cm? (Round
your answer to two decimal places.)
W =

cm and 40 J are needed to stretch it from 17 cm to 21 cm, what is
the natural length of the spring?

If 27 J of work are needed to stretch a spring from 10 cm to 16
cm and 45 J are needed to stretch it from 16 cm to 22 cm, what is
the natural length of the spring?
please explain the work

A spring has a natural length of 14 cm. If a 30-N force is
required to keep it stretched to a length of 26 cm, how much work
