tommorow because today im super busssy , check this out it may help :

There is nothing in the pic

There is nothing in the pic

sorry , just search for conservation of energy problems on youtube , it will help a lot

 

[yesow747]

can you repost the pic ?
or share your notes plz ?

It was a link not a pic. , I would really love to help you but i dont have notes its all in my head , just search the internet and i promise you will find answers to all your questions

When section is removed in part ( ii ) , how do we find the area ?
Mark scheme ans :
(2/3 π x 0.6^3 x 3/8 x 0.6) – (π x 0.6^3 x 0.3) + (0.48A x 0.36) = 0, A = 3π /16.
shouldn't area be subtracted ? and why they equated with zero

iii > one mark but seems to be the toughest question ..any solution for it .

this is how personaly i solved the question when i was doing AL
the last part mey be tricky to understand , but you can think of it of balancing a ruler on your finger then removing equal masses from both ends => center of mass is still where it is !

Question 7, Why do we have to obtain and equation with A, B and C ? There are only two denominators so I only obtained with A and B !
Then second part, can anyone solve it for me please?

Part (i) > No idea '
Part (ii) > just tell me what will be distance from centre of mass of triangle to AB &why

I cant solve any one , and cant what is the extension ,
and which is the zero line too

for part ii and iii all you should do is consider the ee and ep and ke at where ap=2.5 and when ap =2.05 which is where ek is max ( ek is always max in equilibrium position) , and btw you can cosider pe =0 at where ap=2.5 as it is the lowest point.
