Statement:
Jane does 5 joules of work when she closes her bedroom window. She applies a force of 6 newtons to do the job.
To find out:
The displacement of the window when she pulled it.
Solution:
- Work done (W) = 5 J
- Force (F) = 6 N
- Let the displacement of the window be s.
- We know, the formula of work done, i.e., W = Fs
- Putting the values in the above formula, we get
- 5 J = 6 N × s
- or, s = (5 ÷ 6) m
- or, s = 0.83 m
Answer:
She pulls the window by 0.83 m.
