MECHANICS PAPER (M1) - COMPLETE SOLUTION - MAY/JUNE 2002
This video is long compared to normal length. I give a complete solution to the Mechanics Paper of year 2002 May-June examination. Each question is thoroughly dealt with.
In order to assist you to skip to the question of your choice, just hover the cursor over the video scroll bar.
I have also included the chapters where I have highlighted major concepts where the examiner has given hints.
However, I would recommend that you watch the complete video several times.
If you find this video useful, I have provided a link to my complete course in MECHANICS 1 where I teach these concepts to more details.
Here is the link to the course:

The second question part 3 is wrong. The answer should have been 7.19N (3s.f.). That can be proved using the sine rule. I noticed that for the 10cos106.3, the value should have been -2.81 (3s.f.) and when you add that to the 10N you should get 7.19N
