Just a small note in question ten u circled the wrong answer. Though thx a lot for the videos. There seems to always be one or two questions i cant do like the pulley on each exam. Im trying to get a perfect score. Do you know how i can fix that?
Oops, thanks for pointing the mistake out. I'll make sure I put a remark in the description for Question 10. If you know what type of questions you normally struggle with then try to do more exercises on that particular topic. Topical exercises will be useful. Hope this helps and all the best for your exam!
We cannot apply v=u+at directly to the initial velocity as it has two components. That’s why we have to find the final vertical velocity using that formula first, then only use Pythagoras theorem.
Moment is product of force and perpendicular distance. Since distance d is horizontal, only the vertical component of the force will produce a moment. That’s why I resolve F to vertical component then multiply by d.
