Jolie is on the weightlifting team at her school. She must lift as much weight as possible from the ground to a standing straight position. How much work will Jolie do if she uses a force of 5N to lift 150 pounds to a height of 1.5m? 0 2.3) O 6.5) 7.5) 0 3.3)

=7.5J

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
