.. The weight of the loaded sled isΒ 2200 N. The coefficient of friction isΒ 0.15. How hard must the dogs pull so that their effort just equals the frictional force? ... to move after the light changes from red to green A team of dogs pulls a sled across the snow. ... 2) pulling force of dogs fL = us N =Β 0.15Β x2200 = 330Β N

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.
