A 35-kg trunk is dragged 10 m up a ramp inclined at an angle of 12 degrees to the horizontal by a force of 90 N applied at an angle of 20 degrees to the ramp. At the top of the ramp, the trunk is dragged horizontally another 15 m by the same force. Find the total work done.

My work:

W=90(15)cos32

=1144.86

W=343(10)cos78

=713

713+1144.86

=1857.9971

The answer in the book is 2114 J. How do I get this?
