Describe the motion of a body which is accelerating at a constant rate of 10 m s–2. If the body starts from rest, how much distance will it cover in 2 s?

The velocity of this body is increasing at a rate of ’10 metres per second’ every second.
Initial velocity, u = 0 m/s
Time, t = 2s
Acceleration, a = 10 m/s2
Using, s = ut + \(\frac{1}{2}at^2\)
= 0 x 2 + \(\frac{1}{2}\) x 10 x 2 x
= 0 + 20 = 20 m
