Final answer:

Jolie will do 7.5 Joules of work.

Step-by-step explanation:

To calculate the amount of work Jolie will do, we can use the formula:

Work = Force x Distance

In this case, the force is 5N and the distance is 1.5m. However, we need to convert the weight from pounds to Newtons. 1 pound is approximately equal to 4.45 Newtons, so 150 pounds is equal to 667.5 Newtons.

Now we can calculate the work:

Work = 5N x 1.5m = 7.5 Joules

Therefore, Jolie will do 7.5 Joules of work.

Answer:

=7.5J

Step-by-step explanation:

Step one:

given data

the applied force F=5N

the distance = 1.5m

Step two:

Required

work done by Jolie

Now by definition, the work done is the applied times the distance which the force is applied

Wd= F*D

Wd= 5*1.5

Wd=7.5J

If she uses a force of 5N to lift 150 pounds to a height of 1.5m, the work done will be 7.5J
