Do car safety questions get much harder than question 5 on this paper? http://www.ocr.org.uk/Images/58048-question-paper-unit-g481-mechanics.pdf

I thought that was a really nice question

clockwise moments= W x 0.15 W=ma=45x9.81 (45x9.81) x 0.15= F x 0.600
rerange to find f and thats it

Yh theres not much more they can to be honest its just rephrasing the same question
Good luck everyone, ive got a feeling there will be an Aristotle-Galileo question. Hasnt been one for a few years:smile:

Hoping for a hard mechanics paper & easy EWP.
Oh no! I've just realised that the only people who are gonna be doing this exam are resitting! These grade boundaries gonna be rough!
june 2009 g481 Q5 aii any one know why the answer is not F=W/sin(theta)

but isn't the weight force not perpendicuar it looks like there is some component.

resolve and use trig

it looks like it doesn't it, but it is the perpendicular distance so
zzxxDash53xxzz was correct

When do you write the answer that force is perpendicular to motion ?

Anyone else freaking out about the exam today?
I ran out of time and only just managed to finish, couldn't check my answers. :frown: but I think it went ok!

How did everyone else find it?

Would like to start an unofficial mark scheme but can't remember a thing!!
I thought it went well. Did anyone get approximately 23mm for the penultimate question?

I think so
Did anyone else get approx 23 cars for the motorcyclist jump question?
I got a lot of cars jumped by the motorbike, like 23. seemed a lot of cars to jump over
