How to solve Kinematics problems

Motion in a Two dimensional Plane

Select a coordinate system and resolve the initial velocity vector into x and y
components.
Find out acceleration in each direction and solve in each direction according to one rectilinear motion equation.
if the acceleration is in vertical direction only.Follow the techniques for solving constant-velocity problems to analyze the horizontal motion. Follow the techniques for solving constant-acceleration problems to analyze the vertical motion. The x and y motions share the same time of flight t.

What is inequalities
In mathematics, an inequality is a relation that holds between two values when they are different
Solving linear inequalities is very similar to solving linear equations, except for one small but important detail: you flip the inequality sign whenever you multiply or divide the inequality by a negative

Symbols used in inequalities

The symbol < means less than. The symbol > means greater than.
The symbol < with a bar underneath means less than or equal to. Usually this is written as ? The symbol > with a bar underneath means greater than or equal to. Usually this is written as ?
The symbol ? means the quatities on left and right side are not equal
