Let a uniform circular disc of mass m and radius R is free to rotate in Horizontal Plane about a Point "O" at the edge ( Hinge at the Point "O" ) . A Man Having Same Mass m is standing at the point "A" which is just opposite diametric end point with respect to point "O" .
Now at time t=0 , man Starts moving with Constant velocity "" with respect to disc.
Then Find The angular displacement of the disc ( ) in the time interval when Man reaches again at point "A" at the disc.
If Your answer is and it is expressed as :
Then Compute " a + b " ?
'a' and 'b' are co-prime positive integers.
Man moves on circumference of disc only.
