By the end of this month - May, I am planning to complete the very first portion of Physics, Mechanics, out of eight different portions. Underneath this post, and in this thread, the solutions of questions of the past fifteen years related to Mechanics will be posed. The basic aim of this thread will be to have a discussion regarding the different facets of the subject-matter and to save the past papers' solutions.

All those who are going to opt Physics as an optional subject will be welcomed for sharing the stuff related to the portion, Mechanics, shared below with the bullet "I."

NOTE: Please do not comment below if you have any unrelated thing to share. (Sorry for an orange colour, as red is reserved for moderators maybe; but I hope you will not skip this important note)
