i want to know this too

73.3 or 73.6 please do the calc again it was ->>>>>3ms and 10 down so arctan 10/3

I put square root 109, would I only lose 1 mark or more?

Yeah I got exactly 15 too! Wonder what I did wrong..

How many marks do you think I'd get for putting in the wrong limits? 3 and 4 (it was 5 marks)

Should be -1, nothing to lose sleep over.

I would think that you would probably lose one or two A1 marks for it, assuming your method was correct (I would think it might be M1A1 for getting the correct integral, M1 for subbing in values and solving).

suvat

horizontal: s=lambda
vertixcal: s=-lamda

Fill in the other knowns, find t in terms of lambda using the horizontal (t=1/3 lambda) and then solve substituting this into s=ut+1/2 at^2 with the vertical values

Did anyone else get 1.22 as their distance for the centre of mass?

Like i said dude some ms allow student to leave answer as root form. You may be right so

Hmmm I did this, must have made a slip somewhere. Thank you

I put square root 109, would I only lose 1 mark or more?

The question was 6 mars so I 'd say you got 3 and lost 3.

5 marks* so would i get 2 marks?

You're welcome to contribute, as I can't remember all of it.
