distance travelled in 1st second=20m

time taken to travel this distance=1s

So speed in first second is dist/time = 20m/s

Similarly speed in 2nd second is 40m/s

Now acceleration = dv/dt

Here dv means change in v, where v is velocity and dt means change in t where t is time interval.

Change in velocity = final vel. — initial vel.

That is, 40-20 = 20m/s

And change in time = 2 — 1 = 1s

So acceleration is 20m/s / 1s = 20m/s^2 Ans.

Metre per second square is the standard unit of acceleration.
