a particle of mass m is attached to a disc of equal mass m by means of a slack string - Physics -

Question

a particle of mass m is attached to a disc of equal mass m by means
of a slack string The disc is hinged about its center C on a
horizonal smooth table The particle is thrown on horizontal table
with initial velocity v Find its velocity, when the string becomes
taut

Dear student

when the string become taught, the disc and the mass will have same velocityby conserving momentum,mv=2mVV is final velocityV=v2
