Question

In a tug-of-war two teams are pulling in opposite directions, but neither team ismoving. What do the net forces equal in this example?

Answer 1

so, the net forces equal zero

Step-by-step explanation

Step 1

Draw the situation

Newton's first law says that if the net force on an object is zero, then that object will have zero acceleration

in this case due to neither team is moving, we can say the center point is at rest,so its acceleration is zero

According to Newton's law, as the object is at rest, the sum of the forces acting on it equals zero

so

sum of forces = 0

the forces are due to the teams pulling so,

`\begin{gathered} \text{Force team 1 -force team 2= 0} \\ \text{if we move the second term to the rigth} \\ \text{Force team 1=Force team }2 \end{gathered}`

so, the net forces equal zero
