Question

Two forces are acting on an object
F1: 13 N 57.5^o
F2: 23.5 N 12.3^o
Which of the following statements are true? Why? (select all that apply)

A. The object could remain stationary

B. The object could move with constant velocity

C.The object would experience a net force

D.The object would accelerate

Suppose F1 in the problem above was rotated so that it pointed in exactly the opposite direction as F2. Assume F2 is unchanged in direction, and assume both forces are unchanged in magnitude. How would rotating F1 change the net force? Why?

A.It would make the magnitude of the net force smaller, since the forces will no longer be partially aligned.

B.The net force would have a magnitude of zero since the forces are now pulling in opposite directions.   

C. It would change only the direction of the net force; its magnitude would remain unchanged.

D.It would change only the magnitude of the net force; its direction would remain unchanged.
