To determine which car will require the longest time to come to a full stop, we need to consider their speeds. The car with the highest speed will take the longest to stop, assuming they all have the same mass and decelerate at the same rate.
The given speeds for the cars are:
- 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]
By examining these speeds, we can determine which car has the highest speed.
- 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]
Among the listed speeds, Car D has the highest speed at [tex]\(895 \, \text{m/s}\)[/tex].
Therefore, since Car D is the fastest, it will require the longest time to come to a full stop.
The correct answer is:
D. Car D
