Circular motion...

JEE Main 2015 Guidance › Mechanics questions › Circular motion...

A particle moves in a horizontal circle with vel. v at the end of an inextensible string.If it collides elastically with a straight wall when the string makes an angle 'x' greater than pi/4 with the wall,
then its velocity when it resumes circular motion is
a.v b.vcosx c.vcos2x
