0.697 or something

I got 0.71 so pretty similar :smile:

:smile:

That Bike frictional forces question :,(

Can someone give me a list of all the questions that come ish I feel like I only did 7 long questions when there were 8

0.69 ms ?

I got 0.59

What did everyone put down for the question that asked why PD would be slightly less than 5V - I said internal resistance but quite a few people said contact resistance (which would make more sense as the advanced information said Core practical 2 and this is part of it)

I talked about internal resistance as well they probably both have an effect tho

And what points did people put down for the trend between angular velocity and turning effect question?

Did anyone work out the power question at the beginning

i said internal resistance

I got 214 watts

Not me :/

I got the same

How did u work it out

yea 0.698181 m/s

I got the same

How were you even supposed to do that???

How did u work it out

So the power is force x velocity and force is equal to horizontal component of weight + resistive force

I used GPE equation and W=Fd with the speed instead of distance to give it in terms of Js-1 which would be the same as power I think :smile:

Did u guys do the power question at the start

yeah, came back to it at the end and got 25kW iirc. I used EK equation with horizontal component of velocity

And what points did people put down for the trend between angular velocity and turning effect question?

- F = mrw^2
- Moment = Fx
- directly proportional
