Problem A1:
Consider the three forces shown in the figure. One force is equal to
F1 = -2 i Newtons. A second force is equal to
F2 = n1 i Newtons. A third force is equal to
F3 = n2 j Newtons. If all three forces act
at once, what is the magnitude of the resultant "net" force. That is, if the
magnitude of the net force |Fnet| = n3 Newtons, what is
n3?
