Question

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

Explanation:

Step1: Identify initial and final velocities and time

Initial velocity $u = 4$ m/s, final velocity $v=16$ m/s, time $t = 4$ s.

Step2: Use acceleration formula

The formula for acceleration $a=\frac{v - u}{t}$. Substitute the values: $a=\frac{16 - 4}{4}$.

Step3: Calculate the acceleration

$a=\frac{12}{4}=3$ m/s².
