Explanation:

You need to understand what acceleration means.

Acceleration is the change in your velocity (or speed) over time.

So if you are accelerating at a constant rate of 10 m/s^2, it means your speed is increasing by 10 m/s every second.

You start at rest, which means your starting speed is 0 m/s.

After 1 second, you have accelerated to a speed of 10 m/s

After 2nd second, you have accelerated by another 10 m/s => your current speed is 20 m/s.

So now, you know your final speed, 20 m/s.

Let’s get your average speed => (V1 + V2)/2 = (0 + 20)/2 = 10 m/s

speed = distance/time => 10 m/s = distance/2 s

=> distance = 10 m/s x 2 s = 20 m

U=Om/s

A=10m/s2

T=2s

D=?❓

S = ut +1/2 at^2

=0×2+1/2×10×2×2

=0+1/2×40

=20m Ans.
