Mr. A is pushing a cart with a force of F1 = 15.00 N due north. Mr. B is pushing the same cart with a force of F2 = 25.00 N due northeast. Mr. C is pushing the cart a force F3 so that the cart is in equilibrium. Find force F3 so that . First, we calculate the vector sum by component method. The x-component of ->F1 is ______ and the y-component is _____ . The x-component of ->F2 is _____ and the y-component is _____ . Adding the components, we can express the resultant vector in unit vector component form: ->F1 + ->F2 = _____ ^i + _____ ^j Since we want to find ->F1 + ->F2 + ->F3 = 0 , it follows that ->F3 = -(->F1 + ->F2). Thus, ->F3 = _____ ^i + ______ ^j The magnitude of ->F3 is F3 = _____ N
Supply all missing information with the correct numerical values. Do not include the units. Round off all answers to two decimal places. Do not forget the negative sign (-) if needed.

The x-component of ->F2 is _____ and the y-component is _____ .
Adding the components, we can express the resultant vector in unit vector component form:
->F1 + ->F2 = _____ ^i + _____ ^j
Since we want to find ->F1 + ->F2 + ->F3 = 0 , it follows that ->F3 = -(->F1 + ->F2). Thus,
->F3 = _____ ^i + ______ ^j
The magnitude of ->F3 is F3 = _____ N
