Question #14531

An object has a (vector) displacement, x(t) (in m), as a function of time, t, (in s)
x(t) = A î + B t ĵ + C t2 ĵ + D t3 î Where î and ĵ are dimensionless unit vectors.
What is the velocity of the object as a function of time?
What do the constants A, B, C and D represent? What are their units? Which are scalars, vectors or neither?
