Expert Answer

Step 1

Equations of kinematics for an object moving in one dimension are constructed from the fact that the acceleration of the object is constant. Constant acceleration implies velocity changes with time. Velocity can either increase or decrease with time.

Step 2

Position of the object may increase or decrease with time. Direction ...
