Well K.E is going to be maximum when velocity is maximum, which is when the object is at the midpoint. K.E will be zero when velocity is zero, which is at maximum displacement. Potential Energy = mgh, so it'll be at a minimum when there is no change in height which is at the equilibrium position.
Why is it on every exam paper topic someone always tells us to stop talking about it... -_-. We want to talk about it, that's the whole point of the thread, it'll ease our worrying while waiting for results day.
no problem ermm i think 60 at least, but i may be being kind to myself i dunoo but i would be so happy with that i need 109 UMS for an A but i re-sat unit 4 which i think went well too, so i hope i can get it (<---- sorry for the life story lmao )
Unit 5 is up, Unit 4 will come later. Ill also be making a thread for both the papers (So its easier for people to get to them), but I guess the discussions should stay here.
Edit. Skannan: I also applied for EEE (firmed with UCL). Shame maths went terribly otherwise I may have had a chance.
what is your offer and what grades do you think you are going to get?

How about you?
Well,the super minimum grade i could get is 60/80. I just need 75/100 for each A2 module.
jamo i agree with your answers thanks for mark scheme.
hey no problem thanks for the feedback ... i was scared i was gunna put the mark scheme up and everybody would just be like, nope they're all wrong sorry jamo :P xD
you are correct! We already said that it was wrong in another thread,probably you missed it. How did you do?
i realised now i missed lots of marks because the question were worded tricky, like q11 b i didn't read the vertical bit, if i did i would have used a=9.81
the radioactivity question, they use different units for time in different part of the question, so i messed that up.
oh well the exams are i think i will 60 or above. hopefully thats more than an A. i am guessing A is going to be 54-56, somewhere around there.
