Physics

You use a rope to slowly pull a sled and its passenger 45 m up a 20∘ incline, exerting a 125-N force on the rope.
How much work did Earth do on the sled for the trip in Part B?

The answer for part is -5630 J

I'm not sure what to do. I tried -5630 J * 9.8
then I tried 125N * 45m *9.8 * cos20

I'm not sure what else to try.

Please help
Thank you!

  1. work is ... force times distance

    you have both ... 125 N , 45 m
