s is displacement hear so the dimensions formula of s is [L] We know that we can add and subtract only those quantity which have same unit so dimensions formula of ut and 1/2at² is same Now u is initnial velocity it's dimensions formula is =[LT^-1] And t is time so =[T] ut dimensions formula is [L] The formula s=ut+1/2at² is dimensionally correct
