You are testing a new car using crash test dummies. Consider two ways to slow the car from 90 km/h (56 mi/h) to a complete stop: (i) You let the car slam into a wall, bringing it to a sudden stop. (ii) You let the car plow into a giant tub of gelatin so that it comes to a gradual halt. In which case is there a greater impulse of the net force on the car? Prove and tick below. A. in case (i) B. in case (ii) C. The impuls is the same in both cases. D. The impuls of first case > the impuls of the second case. E. The impuls of first case < the impuls of the second case.

Question
You are testing a new car using crash test dummies. Consider two ways to slow
the car from 90 km/h (56 mi/h) to a complete stop:
(i) You let the car slam into a wall, bringing it to a sudden stop.
(ii) You let the car plow into a giant tub of gelatin
so that it comes to a gradual halt.
In which case is there a greater impulse of the net force on the car?
Prove and tick below.
A. in case (i)
В. in case (ii)
C. The impuls is the same in both cases.
D. The impuls of first case > the impuls of the second case.
E. The impuls of first case < the impuls of the second case.
