Difference between pound and kilogram (kg vs lbs)

Pounds and kilograms are two of the many units used for the measurement of mass. Physical quantities need units for their measurement. We need standard well-defined units for measurement of physical quantities. Although both pound and kilogram are units of mass but there are some profound differences between these two units of mass. A pound

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.
