Question

A free uniform disc of mass m 1 kg and radius R 1 m is rotating on smooth horizontal floor with angular velocity 10 rad s A particle of mass 2 kg is released from height 5 m above disc Particle hits disc at distance R 2 from centre of disc Collision of particle with disc is inelastic and particle sticks to disc after collision due to friction Disc does not bounce from ground during collision of particle with disc 21 22 23 w 10 Top view The friction force acting on particle after impact is A 25 4 N C 50 N The angular velocity of disc immediately after collision is A 5 rads B 10 rad s C 7 5 rad s D 12 5 rad s B 75 4 N D 50 3 N Wo M 1 kg The impulse on particle due to disc during impact is approximately A 20 2 Ns B 10 1 Ns C 10 Ns D 15 Ns side view 2 m h s R 2 and bet ho the Ca CC S C
