Answer:

330 N

Explanation:

In order to calculate the frictional force, you just have to use the next formula:

[tex]Friction=W*Coefficient[/tex]

Now you just have to insert the values into the formula:

[tex]Friction=W*Coefficient[/tex]

[tex]Friction=2,200N*0.15[/tex]

[tex]Friction=330 N[/tex]

So the friction force is 330 N, from the weight and the coefficient of friction with the ground, so the dogs only have to pull with a combined force of 330 N.
