A hydraulic jack is needed to raise an object with a force of 4000 N to a height of 3 metres above the ground. Will the jack do the job? (Answer after working through the rest of the question.

I would really appreciate it if someone would please help me with this question. Thank you.

To determine if the hydraulic jack is capable of raising the object to the desired height, we can calculate the work required.

Work (W) is calculated by multiplying the force (F) applied on an object by the distance (d) over which the force is applied, using the formula:

W = F * d

In this case, the force required to raise the object is 4000 N, and the distance over which the force is applied is 3 meters. Therefore:

W = 4000 N * 3 m

W = 12000 N·m, or 12000 joules

The hydraulic jack will be able to perform the job if it can provide at least 12000 joules of work.
