A smooth ring A of mass m can slide on a fixed horizontal rod A string tied to the ring passes over a fixed pulley B and carries a block C of mass M 2 m as shown in figure 5 W7 At an instant the string between the ring and the pulley makes an angle 0 with the rod a Show that if the ring slides with a speed v the block descends with speed v cos 0 b With what acceleration will the ring start moving if the system is released from rest with 0 30 ART 0 B
