Question

You wish to lift a 720N crate of bricks to the 3rd floor of a building in a construction site. The 3rd floor is 16m high. How much work will that require?

Answer 1

ANSWER

$11,520J$

EXPLANATION

Parameters given:

Weight (force), F = 720N

Height (distance), d = 16m

To find the work required to lift the crate to the 3rd floor, we have to find the product of the force (weight of the crate) and the distance it will be lifted.

Therefore, we have:

$\begin{gathered} W=F\cdot d \\ W=720\cdot16 \\ W=11,520J \end{gathered}$

That is the work that it will require.
