Acar increases from 15 km/s to 45 km/s in 5 seconds. calculate the average acceleration of the car during these 5 seconds.
6 km/s2
12 km/s2
30 km/s2
60 km/s2

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

Substitution

                    a = (45 - 15) / 5

                    a = 30 / 5

                   a = 6 km/s
