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.
