Question

12 formula 1 point a scooter has an initial velocity of 12 m/s. over the course of 5 seconds the scooter comes to a complete stop. calculate the acceleration of the scooter. answer

Explanation:

Step1: Identify the formula

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

Step2: Determine the values of variables

The initial velocity $u = 12$ m/s, the final velocity $v=0$ m/s (since it comes to a complete stop), and the time $t = 5$ s.

Step3: Substitute values into the formula

$a=\frac{0 - 12}{5}=\frac{- 12}{5}=-2.4$ m/s².

Answer:

$-2.4$ m/s²
