Question

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?
○ 0 m/s
○ 2.3 m/s
○ 4.6 m/s
○ 46 m/s

Explanation:

Step1: Recall the formula for final velocity

The formula for final velocity \(v = u+at\), where \(u\) is the initial velocity, \(a\) is the acceleration and \(t\) is the time.

Step2: Substitute the given values

Given \(u = 0\space m/s\), \(a=4.6\space m/s^{2}\), \(t = 10\space s\).
Substitute into the formula: \(v=0 + 4.6\times10\).

Step3: Calculate the final velocity

\(v=46\space m/s\)

Answer:

46 m/s
