The distance travelled by a particle starting from rest

The distance travelled by a particle starting from rest and moving with an acceleration 4/3 ms^–2, in the third second is:

Distance travelled in the nth second is given by t_n = u +	a	(2n - 1)
	2

put u = 0, 4/3 ms^-2 , n = 3

∴ d = 0 +	4	(2 × 3 –1) =	4	× 5 =	10	m
	3 × 2		6		3
