Question

A force of 4.0 N will extend a linear spring 0.02 m(2 cm) beyond its natural length. How much work is required to extend the spring from .02 m(2 cm) beyond its natural length to 0.04 m(4 cm) beyond its natural length? Show all your work. Your work must be correct.

Answer 1

4 Joules

Step-by-step explanation:

Natural length, l= 2cm

New length, L= 4cm

work done, W = ?

from, W=Fe/2

extension, e=?

extension = New length - Original length

= L - l

= (4 - 2) cm

e= 2cm

W = 4 × 2 / 2

8/2

W= 4 Joules
