Verify the correctness of the equations `v = u + at`.

Explanation

In the dimensional form
`[L^(1)T^(-1)]=[L^(1)T^(-1)]+[L^(1)T^(-2)][T^(1)]=[L^(1)T^(-1)]`
The dimension for L on both sides is 1
The dimension for T on both sides is -1
Hence from the principle of homogeneity of dimensions the given cquation is correct.
