Question

The Velocity of a car increases from 15 km/h to 33km/h in 20s. find its acceleration.​

Answer 1

Answer: The acceleration is 0.9

Explanation:

Acceleration = Change in velocity / time

Lets change km to m and h to sec

Therefore 15 km/h changes to 4 m/sec

and 33 km/h changes to 9 m/sec

Lets substitute the values

Therefore 9 - 4 / 20

                = 5 / 20

                = 0.25 m/sec

1.5 m/sec = 0.9 km/h
