Question

1. calculation

a car starts from rest and accelerates uniformly at 3 m/s² for 8 seconds. what is its final velocity?

Explanation:

Step1: Identify the initial velocity, acceleration and time

The car starts from rest, so initial velocity $u = 0\ m/s$, acceleration $a=3\ m/s^{2}$, time $t = 8\ s$.

Step2: Use the kinematic - equation

The kinematic equation $v=u + at$ is used. Substitute the values: $v=0+3\times8$.

Step3: Calculate the final velocity

$v = 24\ m/s$.

Answer:

$24\ m/s$
