Answer 1

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.
