Question

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

Answer 1

Work done, W = 0.0219 J

Step-by-step 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=(1)/(2)kx^2`

`W=(1)/(2)* 290* (0.0123)^2`

W = 0.0219 J

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