A 1000 kg car in neutral gear slow from 15 m/s to a stop in 5.0 s due to the force of friction. A. What was the acceleration of the car. B. What was the car’s initial momentum? C. What was its final momentum? D. What was the change in momentum of the car? E. What was the impulse acting on the car? F. How much force stopped the car? G. What distance did the car travel in coming to a stop? H. What was the average velocity of the car as it came to a stop?

    Surely you know how to compute acceleration given the speed change and time interval. You should also know how to calculate momentum by now.

    If you are not going to make an effort, neither am I.
