The magnitude of a force pulling a box 5 m at a 20 degree angle from horizontal is 68N. How much work is done on the box?

plz help me solve this!

1. That is not the whole problem. To figure out how much work is done we have to know how far the box is pulled.
You did not say but I assume the box is being pulled horizontally so the force in the direction of motion is
68 cos 20 = 63.9 Newtons
The work done by the force in Joules is 63.9 times the distance moved in meters.

2. Multiply the force component Damon provided by the 5 m distance moved and you will have the work done, in Joules
