26= u +(19 a /2) ...(1) 28= u +(21 a /2) ...(2) ⇒ u =7 and a =2

Q. A body covers $26, 28, 30, 32$ metres in $1 0^{th}$ $1 1^{th}, 1 2^{th}$ and $1 3^{th}$ seconds respectively. The body starts :-

From rest and moves with uniform velocity

From rest and moves with uniform acceleration

With an initial velocity and moves with uniform acceleration

With an initial velocity and moves with uniform velocity

$26 = u + \frac{19 a}{2} ... (1)$
$28 = u + \frac{21 a}{2} ... (2)$
$\Rightarrow u = 7$ and $a = 2$
