Fiding the coefficent of friction for work done.

[Exiab]

For some reason despite what attempts i have made my answers are defiantly not coming out right so any help on even proper setup would be appreciated.

Homework Statement

You have done 2.2kJ of work
to push a 78-kg trunk
3.1 m along a slop inclined upward at 22degrees

What is the coefficient of friction between the trunk and the slope

What do you know about the work done's relation with the distance it's moved?

What can you get out of re-arranging the work formula?

Ok i managed to work it out, just took me longer than I liked.

Thank you.
