    GUYS! HERE'S A TIP. When you're writing the answers for any questions related to the effects of ICT. You're allowed to give modern day examples etc, stuff that might not be in the marking scheme. Due to the fact that Ict is a subject of technology. This was cited by a CIE examiner.

    The question said estimate not calculate, So I completely disregarded using the cone formula. What I did was take the volume of the entire pencil as if it were a cylinder, using the formula they gave and subtract the volume for Ve. There's no saying if what if what any of us did was right or...

    There's two ways to do it. Go under E and then up or go above E and then down. First, Start at B. You want to get directly above D, so you go -a two times. = -2a. Secondly to go from this point to E, you have to go -c twice. = -2c. Final vector = -2a - 2c

    Alright here goes. First of all part a) is asking you to convert from kilometres per hour to metres per second. 1 kilometre= 1000 metres. 144 kilometres = 140 x 1000 = 144,000 metres now convert the hours to seconds. 1 hour = 60 minutes. 1 minute = 60 seconds. So 60 minutes = 60 x 60...

    Ok position vector means going from the origin to the letter. The origin is always O. So you have to go from O to E. First of all the lets get under E. To get under E, You go -b from O and now you're under E. To get to E we just add c, because c is going straight up vertically.

    I just showed you how to do it... look for it.

    -b will get you to a point under E. To get to E just add c. so -b+c. Is that the answer?

    Ok you got the base ABCD. Find the length of the diagonal DB. Which is √(10^2+10^2) according to Pythagoras. You should get 14.1. Now half of this will give you MB which = 7.05. You already have PB = 8. Use Pythagoras again. MP = √(8^2 - 7.5^2) MP = 3.78 cm.
