# A wagon is pulled by a force of 60 pounds on the handle at an angle of 45 degrees to horizontal. What is the work done in moving the wagon 50 feet up a 15 degree hill?

##
I know how to find work in pulling the object horizontally. I don't know what changes when I pull the object uphill.

Work done

#=>W=|vecF| |vecs| cos theta#

where#theta# is the anlge between force and displacement

Inserting given values and noting from the figure that

#W=60xx 50\ cos 30^@#

#=>W=60xx 50\ cos 30^@#

#=>W=2598\ ftcdotlb#
