Answer from: shanayamcinnis15

330 N

Explanation:

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

Friction=W*Coefficient

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

Friction=W*Coefficient

Friction=2,200N*0.15

Friction=330 N

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.
