Chapter 8.1, Problem 8.1TYU

Rank the following situations according to the magnitude of the impulse of the net force, from largest value to smallest value. In each situation a 1000-kg automobile is moving along a straight east–west road. The automobile is initially (i) moving east at 25 m/s and comes to a stop in 10 s; (ii) moving east at 25 m/s and comes to a stop in 5 s; (iii) at rest, and a 2000-N net force toward the east is applied to it for 10 s; (iv) moving east at 25 m/s, and a 2000-N net force toward the west is applied to it for 10 s; (v) moving east at 25 m/s; over a 30-s period, the automobile reverses direction and ends up moving west at 25 m/s.
