I found out the extension
As GPE is completely transferred to EPE, I took it to be the EPE
Then I used EPE=Tension*extension

I didn't use 0.5 as I got stuck with the concept of Energy transferred=Force*displacement

Most of the questions required thorough analysis before answering, it wasn't all that tough. That being said there just wasn't enough time to think and answer! I just had 15 mins on the clock when I came upon #17. :frown:

Was the tension somewhere around 700N? I dont remember the exact value.

mine was 1875 :/ (using the show that value)

Mine was 0.4 something too
Does that mean the goal was scored or not?

I don't know whether is there a thread for 2015 Jan Edexcel IAL Physics exam or not but I just open a new one.

So, for people who took the exam today, how was it? :confused:

happens to be the ****tiest exam ever... I will owe edexcel one if I just get a B or C.... :frown:

I am confused about the magnet question.Can you please say what'll be the answer here?

it had to do with newtons third and first law,because the attractive forces cancel each other out the car cannot accelerate.So by newtons first way an unbalanced force is required to move or accelerate the car.I forgot to mention about the third law i guess they'll probably cut out 1 mark
