Answer:

The answer to your question is 6 km/s

Explanation:

Acceleration is a change in velocity with respect to time, its units are m/s² or km/h².

Data

vo = 15 km/h

vf = 45 km/h

t = 5 s

Formula

            [tex]a = \frac{vf - vo}{t}[/tex]

Substitution

                    a = (45 - 15) / 5

                    a = 30 / 5

                   a = 6 km/s
