Rod can rotate about hinge point 'P'. A ball of mass 'm' is projected with a velocity `5v_(0) ` in a gravity free space as shown in figure. Collision between the rod and the ball is perfectly elastic. Then find the magnitude of velocity of ball after the collision ( neglect the friction between the ball and the rod during the collision ).

A

`sqrt((649)/(49))v_(0)`

B

`sqrt((865)/(49))v_(0)`

C

`sqrt((563)/( 49))v_(0)`

D

`sqrt((772)/(49))v_(0)`
