s=600m
u=20m/sec
a=5m/sec^2
t=?
all 3 derivations
1. v=u+at
2.s=ut+1/2at^2
3.2as=v^2-u^2
let us use the 2 derivation
s=ut+1/2*5t^2
600=20t+1/2*5t^2
600=20t+5t^2/2
taking LCM
600=(40t+5t^2)/2
taking 2 to the other side and making 2 * 600
1200=40t+5t^2
1200/40=t+5t^2
30/5=t+t^2
√6=t+t^2
time =2.44sec
u=20m/sec
