Question

type the correct answer in the box. a car accelerates from 4 meters/second to 16 meters/second in 4 seconds. the cars acceleration is meters/second².

Explanation:

Step1: Recall acceleration formula

The formula for acceleration $a=\frac{v - u}{t}$, where $v$ is final - velocity, $u$ is initial - velocity, and $t$ is time.

Step2: Identify values

Given $u = 4\ m/s$, $v = 16\ m/s$, and $t = 4\ s$.

Step3: Substitute values into formula

$a=\frac{16 - 4}{4}=\frac{12}{4}=3\ m/s^{2}$
