Detailed Solution

s = 180 m,t = 6 sec,v = 45 m/s

$a = ?, u = ?$

$s = vt - \frac{1}{2} {at}^{2}$

$180 = (6) (45) - \frac{1}{2} a {(6)}^{2}$

$180 = 270 - 18 a$

$\Rightarrow 18 a = 270 - 180 = 90$

$\Rightarrow a = 5 {m/s}^{2}$

$a = 5$

$\frac{v - u}{t} = 5$

$\frac{45 - u}{6} = 5 \Rightarrow 45 - u = 30$

$\Rightarrow u = 15 m/s$
