The change in momentum of an object is given by the formula:
Change in momentum = Force * Time
In this case, the force of friction is slowing down the car, so the force is opposing the motion and is negative. Thus, we have:
Change in momentum = (-2600 N) * (6.00 s)
Change in momentum = -15600 Ns
Since momentum is a vector quantity, the negative sign indicates the change in direction of the momentum.
