Please give basics of kinematics and vectors displacements.

It's impossible to give "the basics" in a forum like this. Read the chapter in your text and if you have specific questions, ask. But essentially it all boils down to:

$\vec v = \frac {d \vec s}{dt}$

$\vec a = \frac {d \vec v}{dt} = \frac {d ^2 \vec s}{dt^2}$

Note that s, v, and a are all vectors, and hence much of kinematics is involved with the mathematics of vectors.
