Question
How much work is done in lifting $450 \mathrm{lb}$ of cement $75 \mathrm{ft}$ above the ground?
Step 1
The work done (W) on an object when a force (F) is applied to it is given by the product of the force and the distance (d) over which it is applied. Mathematically, this is represented as: \[ W = F \cdot d \] Show more…
