A 35-kg trunk is dragged 10 m up a ramp inclined at an angle of 12º to the
horizontal by a force of 90 N applied at an angle of 20º 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 attempt: (10)(34)cos(70) = 1173J

Textbook answer: 2114J
