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.

When you jump from an elevated position you usually bend your knees upon reaching the ground. by doing this, you make the time of the impact about 10 times as great as for a stiff-legged landing. in this way the average force your body experiences is a) less than 1/10 as great. b) more than 1/10 as great. c) about 1/10 as great.d) about 10 times as great.
