A dog team driven by an Inuit hunter pulls two toboggans (Figure 1.49).

The dog team can apply a maximum force of 700 N. Each toboggan

experiences a constant frictional force of 100 N.

a) Determine the acceleration of the two toboggans, if each has a

mass of 300 kg.

b) What is the force in the rope joining the two toboggans together?

I know how to calculate the acceleration if there's no friction. Fnet=ma. 700N/600kg=a, but how do you do it if there's frictional force?
