The question is incomplete. Here is the complete question.
What happens when two unbalanced forces act on an object?
Consider a game of tug of war between Tim, Elena and Anne. Tim can pull with a force of 70N, Elena can pull with a force of 100N and Anne can pull woth a force of 30N. Determine if the different configurations of teams are balanced or unbalanced. write the configuration of teams in the correct row.
Balanced
Unbalanced
- Tim versus Elena and Anne
- Elena versus Tim and Anne
- Anne versus Tim and Elena
Answer:
- Tim versus Elena and Anne: unbalanced
- Elena versus Tim and Anne: balanced
- Anne versus Tim and Elena: unbalanced
Step-by-step explanation: In a game of tug of war, the opposing teams pull the rope in opposite direction. If there is equilibrium in the forces, i.e., the opposing forces are balanced and the force resultant is 0, there is no winner.
If the pulling force of one side is bigger than the other, i.e., if there is a desequilibrium, the opposing forces are unbalanced and whichever is greater wins the game.
In the cases described, suppose the positive direction is towards the right side.
1) Tim x Elena and Anne: there is no equilibrium because the force Tim pulls is smaller than Elena and Anne combined and so, the forces are unbalanced.
Force = 70 + (-100-30)
Force = -60N
2) Elena x Tim and Anne: Here the forces result in equilibrium, so they are balanced.
Force = 100 + (-70-30)
Force = 0
3) Anne x Tim and Elena: Force of one side is greater than the other. So, there is no equilibrium and so, the forces are unbalanced.
Force = 30 + (-100-70)
Force = -140N
