Answer 1

In this scenario, since the dogsled is moving at a constant speed in a straight line, it is in a state of dynamic equilibrium. This means that all the forces acting on it are balanced.

In particular, the forward pull of the dogs must exactly balance the backward pull of friction. Therefore, the correct response is:

**The forward pull of the dogs balances the backward pull of friction.**
