Explanation:
Whenever an object is moving in a 2D frame,its motion can be analysed as if it is travelling in two independent 1D frames.
One of such independent 1D frames are along horizontal and another along vertical.
Let
be the total velocity.
Given that,
We call the horizontal velocity as
and the vertical velocity as
.
=

where
is the angle between the object and horizontal.
It is given that
