What about the correctness about the relation,

s_{t}=u+0.5a(2t-1), both dimensionally or any other

Prakash Adhikari asked

**Answer**

The equation refers to the displacement in the **t**^{th} second and hence it should have the dimensions of speed; since it is the **displacement in one second**.

Under this consideration, the equation is dimensionally and otherwise correct.
