Question

Two teams of girls are having a hug of war and neither side is winning. Each of the four girls on the west team is pulling with a force of 250. N. Three of the four girls on the east team are pulling with a force of 260 N each. With what force is the fourth girl on the east pulling.

Answer 1

Answer:

220N

Explanation:

Given that the first time has 4 girls

each girl pull at 250N, therefore the total force

250X4= 1000N

For the second team, the three girls out of the four pulls at 260N each,

let the fourth girl pulls at xN

the total force is 3X260+x

=780+x

we know that the total force on the west must equal the total force on the east

so

1000=780+x

solving for x we have

x=1000-780

x=220N

Therefore the fourth girl on the second team pulls at 220N
