I know how to do this when just given a parabola and points but I'm confused how to work it backwards. I need help going through the process not just the answer.

It was like a myth that it was standard procedure to stand under doorplaces during earthquakes, but my architecture teacher told our class that this is where most bodies are found after a wreckage. He told us that he would tell us another day what to do, but I must have been absent or something, but the class ended then I said, whatever happened to his answer? So I hope I can get it here thanks.

Me and my mom are having a little trouble on them for my homework, I tried them for hours, but a lot of the step-by-step example problems don't relate to the problems I'm struggling with. It's pretty hard being in Algebra 2 and being a freshman, so I'd really appreciate any answers.

And please no "Just do it, beach." Thanks for your answers. ;)

When I compare my answer to the solution manual, I got wrong.
I couldn't get the answer.

The answer is...

F x d = -100 x 9.8j x (-5√3i-5j) = 4900 N.m.

Do you get the answer of 4900?
I used the calculator and I got 13387.04 or just 13387.
Please help me to find the correct answer.
