Answer :
To determine which car will require the longest time to come to a full stop, we need to consider the speeds of each car. The car with the highest speed will take the longest time to come to a full stop, assuming that all other factors such as mass and braking force are the same.
Let's analyze the given speeds of each car:
- Car A: [tex]\( 890 \, \text{m/s} \)[/tex]
- Car B: [tex]\( 850 \, \text{m/s} \)[/tex]
- Car C: [tex]\( 790 \, \text{m/s} \)[/tex]
- Car D: [tex]\( 895 \, \text{m/s} \)[/tex]
- Car E: [tex]\( 870 \, \text{m/s} \)[/tex]
We see that Car D has the highest speed of [tex]\( 895 \, \text{m/s} \)[/tex]. Therefore, Car D will require the longest time to come to a full stop.
The correct answer is:
D. Car D
