Select the correct answer.

Five race cars speed toward the finish line at the Jasper County Speedway. The table lists each car's speed in meters/second. If each car has the same mass, which car will require the longest time to come to a full stop?

\begin{tabular}{|c|c|c|c|c|}
\hline
Car A & Car B & Car C & Car D & Car E \\
\hline
[tex]$890 \, \text{m/s}$[/tex] & [tex]$850 \, \text{m/s}$[/tex] & [tex]$790 \, \text{m/s}$[/tex] & [tex]$895 \, \text{m/s}$[/tex] & [tex]$870 \, \text{m/s}$[/tex] \\
\hline
\end{tabular}

A. Car A
B. Car B
C. Car C
D. Car D
E. Car E



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
