Answer :

This stone is kicked horizontally, thus its initial velocity is zero on the horizontal axis (v 0y=0v 0y=0), and in the absence of air resistance, the stone moves according to the equation of motion shown below:

What is an easy way to define velocity?

Velocity is a vector representation of a particle's or object's motion with regard to time. The recognized unit of magnitude for velocity is the m / sec (m/s), sometimes known as speed.

Why does velocity formula exist?

According to the equation v = s/t, velocity (v) is a scalar quantity that quantifies displacement (and change in position, s), over change in time (t).
