Resources for Vertical Projectile Motion

[Zakariyya]

Hello

I am in my final year of schooling in South Africa. For Physics, we do a module called Vertical Projectile Motion & Graphs. This section uses equations of motion etc.

I cannot seem to find the online resources for me to truly master this section.
The sites I have are of projectile motion when an object is projected at an angle etc
I attach the few of the past papers to show what type of questions we get on this section.
The questions are Questions 3 in the 2015 & 2016 papers

Answers are provided as well

Thanks!

What is it that you want to master about vertical projectile motion? Vertical projectile motion can be treated as one-dimensional motion with the coordinate axis tilted by 90 degrees.

Pretty much everything. I want problem equations with 2 objects and one is projected a second after the other, as in the 2 questions I gave.
I struggle with drawing graphs and understanding the meaning of choosing a certain point as reference.
To me, this section is trickier than Newton's Laws, Work and Energy, and Momentum

A standard Intro physics textbook such as University Physics (Sears/Zhemansky) or Resnick/Halliday will have an explanation.

On the internet, the openstax physics book has a section(2.7) : http://www.saylor.org/site/wp-content/uploads/2013/02/PHYS101_OpenStaxCollege_College-Physics.pdf

Hope it helps.
