Question

 A car increases its speed from 10m/s to 20 m/s in 10 second, its acceleration is 

Answer 1

Answer:

Acceleration = 1m/s²

Explanation:

We know that,

Acceleration = a = Change in velocity / Time

Given

Initial velocity = u = 10m/s

Final velocity = v = 20m/s

Time taken = 10s

Hence

Change in velocity = Final velocity - Initial velocity

                               = 20 - 10 = 10 m/s

Therefore,

Acceleration = 10/10

                     = 1m/s²
