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: Identify the formula

Use the formula $v = v_0+at$, where $v$ is final - velocity, $v_0$ is initial velocity, $a$ is acceleration and $t$ is time.

Step2: Substitute the values

Given $v_0 = 0\ m/s$, $a = 4.6\ m/s^2$, and $t = 10\ s$. Substitute into the formula: $v=0 + 4.6\times10$.

Step3: Calculate the result

$v=46\ m/s$.

Answer:

D. 46 m/s
