5

The following three forces acted on a crate.

F1 = N [N40ºW]; F2 = N [N20ºE]; and F3 = 20 N [S]. What was magnitude of the net force (in N) on the crate?


6
How many degrees north of west was the net force in the previous question?

7
Two children pulled on a wagon by means of separate ropes. One child pulled with a force of 200 N, and the other pulled with a force of 150 N. The two ropes formed an angle of º. What was the magnitude of the net force (in N) on the wagon?

8
How many degrees from 200 N force was the net force in the previous question?
