a car moving south speeds up from 10 m/s to 40 m/s in 15 seconds. what is the cars acceleration?\n2 m/s²\n15 m/s²\n30 m/s²\n50 m/s²
Answer
Explanation:
Step1: Identify acceleration formula
Acceleration $a=\frac{v - u}{t}$, where $v$ is final - velocity, $u$ is initial - velocity, and $t$ is time.
Step2: Define values
$u = 10\ m/s$, $v = 40\ m/s$, $t = 15\ s$.
Step3: Substitute values into formula
$a=\frac{40 - 10}{15}=\frac{30}{15}$
Step4: Calculate acceleration
$a = 2\ m/s^{2}$
Answer:
A. $2\ m/s^{2}$
