Question

14 if initial velocity of a moving car is 30 m/s and its final velocity is 60 m/s, what is the change in velocity? a 60 m/s b 45 m/s c 30 m/s d 15 m/s e 90 m/s

Explanation:

Step1: Recall the formula for change in velocity

The formula for change in velocity ($\Delta v$) is $\Delta v = v_f - v_i$, where $v_f$ is the final velocity and $v_i$ is the initial velocity.

Step2: Substitute the given values

Given $v_i = 30\ m/s$ and $v_f = 60\ m/s$. Then $\Delta v=60 - 30$.

Step3: Calculate the result

$60 - 30=30$.

Answer:

C. $30\ m/s$
