A METERE STICK WEIGHING 240g IS PIVOTED AT ITS UPPER ENDIN SUCH A WAY THAT IT CAN FREELY ROTATE IN A VERTICAL PLANE THROUGH ITS END. A PARTICLE OF MASS 100g IS ATTATCHED TO ITS UPPER END OF THE STICK THROUGH A LIGHT STRING OF LENGTH 1M . INITIALLY, THE ROD IS KEPT VERTICAL AND THE STRING HORIZONTAL WHEN THE SYSTEM IS RELEASED FROM REST . THE PARTICLE COLLIDES WITH THE LOWER END OF THE STRING AND STAYS THERE. FIND THE MAXIMUM ANGLE THRU WHICH THE STRING RISES.
ANSWER - 41
THIS SUM IS FROM HCV SUM NO 68 PG NO 199
I KNOW THIS THING
THAT THE ANGULAR AND LINEAR MOMENTUM WILL BE CONSERVED
BUT IN THE STARTING THE SYSTEM HAS NO ANGULAR MOMENTUM SINCE THE PARTICLE HAS NO VELOCITY .
AND THERE IS ALSO ENERGY LOSS SINCE IT IS AN INELASTIC COLLISION
PLS SOLVE IT

"YOU R THE BEST ONLY WHEN U DEFEAT THE BEST AT HIS BEST"
From J.R.R. Tolkien's 'The Lord of the Rings':
All that is gold does not glitter
Not all who wander are lost
The old that is strong does not wither,
Deep roots are not reached by frost.
From ashes a fire shall be woken
From shadows a light shall spring
Renewed shall be blade that's broken
The crown less again shall be king.

SEE I HV SLVED IT TO SOME EXTENT
JUST VERIFY WETHER THEY R RIGHT AND IF THERE IS A FLAW THEN CORRECT IT
FIRST CALCULATE THE ANGULAR MOMENTUM AND LINEAR MOMENTUM AT THE CENTRE OF MASS WHEN THE MASS REACHES THE BOTTOM MOST POINT OF ITS PATH.
THIS IS BEFORE THE COLLISION
1/2MV^2=MGH WHERE L IS I
V^2=2G
AND THE ANGULAR MOMENTUM IS EQUAL TO MVR
AND AFTER THE COLLISION IT WE CAN CALCULATE THE LOSS IN THE ENERGY OF THE SYSTEM AND THEN FIND OUT THE HIEGHT REACHED
IS MY METHOD RIGHT
PLS VERIFY

SEE DUDES I SOLVED IT BEFORE U COULD
.IT IS SIMPLE JUST CALCULATE THE INITIAL ANGULAR AND LINEAR MOMENTUM AND ON THE BASISI OF THE LAW OF CONSERVATION OF MOMENTUM FIND OUT THE NEW ANGUAR AND LINEAR MOMENTUM. THE MAXIMUM HIEGHT REACHED IS
MGL(1-COS@)=1/2IW^2+1/2MV^2
EHERE I AND W ARE THE NEW ANGULAR AND LINEAR VELOCITIES. PLS VERIFY MY WORKINGS

ONE MORE LAST QUESTION WHENEVER THERE IS A SPHERE OR SOMETHING INSIDE A CUPP OR A BOWL WHY IS THE NORMAL FORCE=MG+MV^2/R
WHY MG IS ADDED
