Hey can anyone tell me where can i get the formula sheet for further maths, please.
this is how personaly i solved the question when i was doing ALView attachment 38846
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 .
Thanks a lot man!
Part (i) > No idea '
Part (ii) > just tell me what will be distance from centre of mass of triangle to AB &why

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