2. A flag pole has three cables pulling as shown from above, with F 300.0 N Î + 500.0 N j, F2 = -200.0 N î, and F3 = -800.0 N j. %3D (a) Find the net force on the flag pole in component form. (b) Find the magnitude and direction of this net force. 3. A 50.0-kg object is initially moving south at 20.0 m/s. Then a force acts on it for 3.00 s, after which it moves northeast, also at 20.0 m/s. What are the magnitude and direction of the average force that acted on the object over the 3.00-s interval? (Hint: Recall, F = mã and ā = A)
