OpenStudy (sweetburger):

Work = Force * DIstance

jabez177 (jabez177):

So 450N x 3, right? Which will get me 1350J So the answer is D?

OpenStudy (sweetburger):

Yea kinda weird that they included the variable time. Its throwing me for a loop.

OpenStudy (sweetburger):

1350J is correct though.

jabez177 (jabez177):
