Question

A car accelerates from 3 m/s to 12 m/s in 20 s.

What is the acceleration of the car?

Answer 1

Answer:

0.45  [m/s²].

Explanation:

1) formula of the required acceleration is (V-final velocity, V₀-initial velocity, t-elapsed time):

$a=\frac{V-V_0}{t};$

2) according to the formula above:

a=(12-3)/20=0.45 [m/s²].
