Work is the measure of the energy transferred when a force is given to the object to move. Work done by the climber is 2,700 Joules.
What is work?
Work is the product of the force applied and the displacement that occurred by the object when given a force. The unit of work is joules and the formula can be given as,
[tex]\rm W = Fs[/tex]
Where W is work, F is force and s is the displacement.
Given,
Force (F) = 90 Newton
Distance (s) = 30 metres
Substituting values in the equation of work:
[tex]\begin{aligned}\rm work &=\rm F\times s\\\\&= 90\times 30\\\\&= 2700\;\rm joules\end{aligned}[/tex]
Therefore, the climber does work of option D. 2700 joules.
