Question

based on the situation described below, how can the acceleration of the car be determined? a car driving with a velocity of +15 m/s accelerates to +20 m/s in 10 seconds. calculate the acceleration of the car. a = m/s² a=(20 m/s - 15 m/s)/(10s) a=(15 m/s - 10 m/s)/(20s) a=(15 m/s - 20 m/s)/(10s) a=(10 m/s - 20 m/s)/(15s)

Explanation:

Step1: Identify initial and final velocities and time

Initial velocity $u = 15$ m/s, final velocity $v=20$ m/s, time $t = 10$ s.

Step2: Apply acceleration formula

The formula for acceleration $a=\frac{v - u}{t}$. Substituting values, we get $a=\frac{20 - 15}{10}$.

Answer:

A. $a=(20\ m/s - 15\ m/s)/(10s)$
