Question

Assertion : The given equation $x=x_0+u_{0}t+\frac{1}{2}a{t}^2$ is dimensionally correct, where$x$ is the distance travelled by a particle in time $t$, initial position $x_0$, initial velocity $u_0$ and uniform acceleration a is along the direction of motion.
Reason : Dimensional analysis can be used for checking the dimensional consistency or homogeneity of the equation.
