s is distance so it's dimensions become L.
Nd other side we have ut+1\2at^2.
Check the correctness of s = UT +1/2at2
s is distance so it's dimensions become L.
Nd other side we have ut+1\2at^2.
as 1\2 is a constant it will have dimensions and apply the dimensions to other quantities.
on solving u will get L there also i,e ur LHS
