You are testing a new car using crash-test dummies. Consider two situations to slow the car from 90.0 km/h to a complete stop: Situation [i]: You let the car slam into a wall, bringing it to a sudden stop. Situation
[ii]: You let the car plow into a giant mound of dirt so that it comes to a gradual halt.
In which situation does the car get a greater impulse of the net force on the car?a) in case (i).b) in case (ii).c) The impulse is the same in both cases. d) The impulse of the first case > the impulse of the second case. e) The impulse of the first case < the impulse of the second case.
