These three cartoon creatures are trying to pull a statue. Graphically find the resultant vector if: The Ant applies 0 The Penguin 0 Jackie Chan 0 Which vector is which? Will it move, and which way will it go ?

For graphical vector addition to work, the arrows must be drawn at exactly the right angle using a protractor and must be drawn to scale (proportionally) using a ruler. Check this drawing with a ruler and protractor The Ant applies The Penguin Jackie Chan

200N 300N 100N 0 Combining the vectors tip to tail, regardless of the order, gives us the resultant. How can we graphically find how big this resultant is?
