Answer 2

Explanation:

V= At² + Bt + C ,

a/c to dimension concepts ,

dimension of v = dimension of At²

[LT-¹] = A[T²]

dimension of A = [LT-¹]/[T²] = [LT-³]

dimension of v = dimension of Bt

[LT-¹] = B[T]

dimension of B = [LT-¹]/[T] = [LT-¹]

dimension of v = dimension of C

[LT-¹] = dimension of C
