Question

the velocity of car increased from 15 km/h to 33 km/h in 20s find its acceleration​

Answer 1

Answer:

0.25 m/s²

Explanation:

Initial velocity, u = 15km/h

                            = 4.166 m/s

Final velocity, v = 33 km/h

                            = 9.166 m/s

Time, t = 20s

We know that acceleration, a = (v-u)/t

So, replacing values, we get = (9.166-4.166)/(20)

                                               = 5/20

                                               = 1/4 m/s²

                                               = 0.25 m/s²

Answer 2

Velocity 1 = 15km/hr = 15/3600 sec

Velocity 2 = 33km/20 sec =
