6. What would the net force be on the box in the problems shown below (tell both force and direction): a. ___________ l 20 N south b. l4 N south 50 N east 70 N west 15 N east 15 N west F' b b 4 T 20 N north l2 N south c. ___________ l 10 N south d. l5 N south 30 N west 60 N west 12 N east 12 N west 4 h ' ' T 7. Look at the following free body diagram and write a brief scenario of what could be represented by this 10 N north TS N north diagram .Label the forces and determine the net force acting on the object . T 20 N SON 5N h b lZON 8. Draw a free body diagram showing the forces acting on a paper rocket sitting on the launch pad (label the names and direction of the forces , but not the magnitude }. 9. Now ,draw afree body diagram of the forces acting on the same paper rocket while it is flying (label the names and direction of the forces , but not the magnitude ). 10. How can a free body diagram help you predict the motion of an object ? Be sure to discuss balanced and unbalanced forces as part of your
