The work done to compress a spring with a force constant of 290.0 n/m a total of 12.3 mm is: a) 3.57 j b) 1.78 j c) 0.0219 j d) 23.6 j

Work done, W = 0.0219 J

Explanation:

Given that,

Force constant of the spring, k = 290 N/m

Compression in the spring, x = 12.3 mm = 0.0123 m

We need to find the work done to compress a spring. The work done in this way is given by :

W = 0.0219 J

So, the work done by the spring is 0.0219 joules. Hence, this is the required solution.
