Jim was playing a tug-of-war game with his two younger twin brothers. Each brother pulled the rope with a force of 30 Newtons. While they were playing the game, the rope didn’t move.
Write the 3 vectors in this situation.
The definition of a resultant vector is the single vector that represents two or more vectors that are acting together.
Goal: Determine why the resultant vector (shown in the diagram to the right) has a magnitude of 114.
Steps
Find the horizontal and vertical components of both vectors.
Write the vectors in component form, ex:
<2,-3>.
Combine the vectors to get the resultant vector by adding the vectors. Add the horizontal component of one vector to the horizontal component of the other vector. Add the vertical component of one vector to the vertical component of the other vector.
Find the magnitude of the resultant vector, which should be approximately 114 Newtons.
Determine the angle of the resultant vector (marked with an á within the diagram).
