Question

Calculate the work done when a mass is lifted vertically by a crane to a height of 10 m, the force required to lift the mass is 120 N.

Answer 1

`1200J`

Step-by-step explanation

We want to find the work done in vertically lifting a mass.

To do that, apply the formula for work done:

`W=F\cdot d`

where F = force; d = distance

Therefore, the work done is:

`\begin{gathered} W=120\cdot10 \\ W=1200J \end{gathered}`
