A box of mass 18.8 kg starts at rest and is pulled by a force of 128 N applied at an angle of 35.0º to the horizontal. There is no friction.
The box is pulled a distance of 18.2 meters.
What is WORK is done on the box?

The force that does the work is the horizontal component of the 128 N force.
F = 128 *cos 35 (105 N)
Work = 128 * cos 35 * 18.2 = 2,329.6 * cos 35
Rounded to three significant digits, the work is 1,910 N * m

work = force * distance = 128 N * cos 35 deg * 18.2 m
