U = 10m/s
a = 5m/s^2
s = 30m
V^2 - U^2 = 2as
= v^2 - (10)^2 = 2*5*30
= (v)^2 = 300 + 100
(v)^2 = 400
V =√400
V = 20 m/s ans.

HEY BUDDY....!!!!
HERE'S THE ANSWER...
_______________________
We know ,
=> v^ = u^2 + 2 a × s
=> v = velocit ( have to find )
=> u = initial velocity. ( 10 )
=>a = acceleration . ( 5 )
=> s = displacement ( 30 )
v^2 = 10 × 10 + 2 × 5 × 30
v^2 = 100 + 300
v^2 = 400
v = √ 400 = 20
HOPE HELPED..
