Question 8 • Physical Science

Ariana is accelerating her car at a rate of 4.6 m/s2 for 10 seconds. Her starting velocity was 0 m/s. What was her final velocity?

Answer
A
2.3 meters per second
B
46 meters per second
C
4.6 meters per second
D
0 meters per second

Explanation

Use the relationship final velocity = starting velocity + (acceleration × time). With a starting velocity of 0 m/s, an acceleration of 4.6 m/s² for 10 seconds gives 0 + (4.6 × 10) = 46 m/s, so the final velocity is 46 meters per second.
