hey friends,
I refer SOLOMONS &FRYHLE FOR ORGANIC CHEMISTRY.BUT I FEEL ITS TOO LENGTHY AND MANY PORTIONS MAY NOT BE IN JEE SLLABI.VERY CONFUSED REGARDING WHAT TO LEAVE AND WHAT TO STUDY.
PLZZZZZZ ANYONE COULD HELP ME?IF ANYONE CAN SEND THE IIT ORGANIC CHEMISTRY SYLLABUS IN DETAIL,IT WOULD BE VERY USEFUL.
REPLY SOON PLZZZZZZZZZZZ.

PLZZZZ SOLVE THIS.
A SMALL BODY ATTACHED TO ONE END OF A VERTICALLY HANGING SPRING IS PERFORMING SHM ABOUT IT'S MEAN POSITION WITH ANGULAR FREQUENCY  AND AMPLITUDE a.IF AT A HEIGHT OF yFROM THE MEAN POSITION THE BODY GETS DETACHED FROM THE SPRING ,CALCULATE THE VALUE OF y SO THAT THE HEIGHT ATTAINED BY THE MASS(H) IS MAX.BODY DOES NOT INTERACT WITH SPRING AFTER DETACHMENT.(awsqr>g

The question is"Asolid sphere rolling on a rough horizontal surface with a linear speed v collides elastically with a fixed,smooth vertical   wall.find the speed of the sphere  after it has started pure rolling in the backward direction."
I don't want the solution.just tell me whats happening there.My approach goes this way.
Let THE SPHERE go rightward with a speed v.friction force acts leftward.for pure rolling v=r.so sphere has to rotate anticlockwise. decreases and also v decreases.at one stage  vanishes.after some time  becomes such that v=r.we have to find the velocity now right?
But i have some doubts.after this (v=r) how can it continue rolling?v decreases and  increases .how can they maintain the relationv=r. 
if it hits the wall before  has vanished thenit is still rotatng anti clockwise and the v becomes leftward.now friction acting rightward increases and v decreases.now will it ever purely roll.
plzzzzz tell me if anywhere i am going wrong.
help me please.

HEY PUNEET BHAIYA,
YOU HAVE STRESSED THE IMPORTANCE OF COACHING INSTITUTE AS IT HELPS IN MAINTAINING REGULARITY.BUT IN MY CITY I DONT FIND ANY GOOD COACHING INSTITUTE.
WHAT DO I DO?WHEN YOU WERE PREPARING FOR JEE DID YOU JOIN ANY?LET ME TELL YOU ONE THING,I THINK I AM SINCERE ENOUGH AND I CAN MAINTAIN REGULARITY ON MY OWN.STILL DO YOU THINK I NEED TO JOIN A COACHING INSTITUTE.IF YES I 'LL TRY IN THE 2ndYEAR.I AM IN 11.PLZZZZZZZZZ HELP.I AM PREPARING FOR IIT-JEE

HEY PRASHANT ,
YOU HAD SENT ME DETAILS ABOUT THE BOOK ON CALCULUS BY SHANTI NARAYAN.BUT I DONT HAVE THAT BOOK.I HAVE 'DIFFERENTIAL CALCULUS FOR COMPETIONS'.ISBN 81-219-2513-4.
WHAT SHOULD I DO? SHOULD I BUY THE OTHER ONE?
IF ANY OF THE MEMBERS CAN HELP ME,PLZZZZZ REPLY.
I MEAN WHICH ONE DO YOU ALL REFER OR TELL ME WHICH ONE IS BETTER?

hey prashant,
you had sent me details about the book on calculus by shanti narayan.but the book i have is not the same.it is 'DIFFERENTIAL CALCULUS FOR COMPETITIONS'BY SHANTI NARAYAN AND P.K.MITTAL.
ISBN 81-219-2513-4
BUT YES THE BOOK YOU HAVE REFERRED IS THERE IN THE LAST PAGES
SO SHOULD I BUY THE BOOK YOU REFFERED?
WELL,IF ANY OF THE MEMBERS REFER TO SHANTI NARAYAN'S CALCULUS ,PLZZZZZZZ SEND ME A REPLY AS TO WHICH SPECIFIC BOOK YOU REFER TO?(GIVE THE ISBN NUMBER)
I 'LL BE VERY GRATEFUL.

A block of mass 1kg is placed on a block of mass 10kgand the bigger block is attached to a spring which is fixed to a rigid wall.spring constant k=200N/m.coefficient of static friction betn the two blocks is 0.40.what amplitude of SHM of the spring-block systemputs the smaller block on the verge of slipping over the larger block?
please sent the final answer as i don't have the final answer.

sir,
actually i bought a book named"differential calculus for competitions"by shanti narayan and pk mittal(S.CHAND AND COMPANY).but there is no hologram on it as it is there in other books of this publication.so,i doubt the authenticity of the book.could you please sent me details of the book of calculus by shantinarayan which everyone refers to as the best on your site.is the book i have bought the same?kindly sent me an answer soon.

sir,
a penguin dives from a uniform board that is  hinged at the left and attached to a spring at the right.the board has a length L=2m and mass m=12 kg,spring constant k=1300N/m.when the penguin dives, it leaves the board and spring oscillating with a small amplitude.assume board is stiff enough not to band.find the period T of the oscillations.
i wanted to know why the torque about the hinge due to the weight of the board is not taken into account.

sir,
could you please tell me that in "fundamentals of physics"by HALLIDAY/RESNICK/WALKER in sample problem 16-6 of ch-16 why the torque due to the weight of the board about the hinge is not considered?

sir,
in resnick,it is written that in the 1985 earthquake in mexico ,as the seismic waves' amplitude increased in the loose soil of mexico city ,it brought about much damage.but why did the amplitude increase in the loose soil?

sir,
please explain the physical meaning of angular frequency in linear simple harmonic motion.i know angular frequency=
[ ]k/m.but what is it's physical significance.

dear experts,
i am a class 11 student.i study in a cbse school where teachers only focus on 12 cbse board.but i want to concentrate on iit .there are also no good coaching institutes here in my city(cuttack in orissa).so i have not joined any.many of my friends have joined chaitanya in vizag.i too want to go there and study for at least one academic year 2007-2008 but my  parents are not willing to send me alone.i feel helpless.please tell me honestly "is it mandatory to  join a coaching institute to get a good rank in iit".can't we study ourselves,follow good books,ask doubts on sites like this one and get a good rank in iit.if not, tell me honestly.in class10,i studied myself and secured 97.6%.cant i repeat my performance in iit?kindly tell me how do i go about my studies from now?please reply soon. the sooner the better.
