Answer:
Here , u = 0 m/s , s = 100 m , t = 5 sec
now,
s = u x t + 1/2 x a x t^2
100 = 0 + 1/2 x a x (5 x 5)
a = 100 x 2/(5 x 5)
a = 8 m/s^2
so value of acceleration will be : 8 m/s^2

I don't understand this q
See , here we use the equation of motion i.e. s=ut+1/2at^2
and we are given with s , t and u so we can find acceleration
Ya 2nd is right
please give 2nd equation answer
Ah... I Didn't understand what you just said
I said your 2nd comment equation is right so... please give me answer
you answer is 8 m/s^2
