Answer 2

Explanation:

_____________

$initial \: velocity \: (u) = 0$

$distance \: (s) = 36m$

$time \: (t) = 4s$

$∴ final \: velocity(v) = \frac{distance}{time} \\ = \frac{36}{4}m/s \\ = 9m/s$

$∴ acceleration \: (a) = \frac{v - u}{t} \\ = \frac{9 - 0}{4}m/{s}^{2} \\ = \frac{9}{4} m/{s}^{2} \\ = 2.25m/{s}^{2}$
