Question

A body starts with inicial velocity 20m/s and accelaration 5m/s^2. Find the distance cover by it in 5sec​

Answer 1

$u = \frac{20m}{s} \\ a = \frac{5m}{ {s}^{2} } \\ t = 5s \\ s = ut + \frac{1}{2} a {t}^{2} \\ s = (20)(5) + \frac{1}{2} (5)(5) \\ s = 100 + \frac{25}{2} \\ s = \frac{200 + 25}{2} \\ s = \frac{225}{2} \\ s = 112.5m$

hope it works
