Question

3.) With the usual notations, check if the following equation
S = u + a(2t-1) is dimensionally correct or not.​

Answer 1

Explanation:

S = u + a(2t-1)

=> S = u + 2at -a

this is not correct.

as the correct one is

S = u + at

if it had '-at' instead of '-a' , then

S = u + 2at - at

=> S = u + at
