Great explanation, I'm watching this before my A Level Exam on Tuesday!

For question 4 why do you take into account theta in terms of only the weight of the bar for the moment of `A but when you are resolving upwards you take theta in consideration at c not the weight and vice versa

[ratofalady]

why is V=3xi + 4xj ? Why wouldn't S(the displacement) be 3i + 4j instead ?? I thought position vector meant displacement ?

[whiteboy]

This isn't at all a criticism, but if it takes you over an hour how are we meant to do it :/

[nitaycarmi]

My only question is for the last question, why do you use subway for horizontal as well?

[rudolffgieseke]

[sas]

How do you know when to give the angle when asking for velocity? Bc sometimes they need it

[RIHN_I]

Amazing explanation bro very helpful to understand the questions 👍

[floryk]

for question 4 why do you only resolve left/right = F at Rc and not at the weight 20g going downwards ???

[oskarwitha_k]

[ysplashy]

50:44 why don't you leave it as a vector?

[thefuturedrmedic]
