The smooth ring A can slide on a fixed horizontal rod as shown the pulley is fixed. If some instant velocity of ring is v, find the velocity of block at that instant.

Two blocks are connected by an inextensible string as shown. The pulley is fixed. If block A moves down with speed v, find the velocit of block B at instant.

Find velocity of block 'B' at the instant shown in figure.

Find velocity of block 'B' at the instant shown in figure :

If block A is moving horizontally with velocity v_(A) , then find the velocity of block B at the instant as shown in fig.

If block A is moving horizontally with velocity v_(A) , then find the velocity of block B at the instant as shown in fig.

A ring of mass m is attached to a horizontal spring of spring constant k and natural length l_0 . The other end of the spring is fixed and the ring can slide on a horizontal rod as shown. Now the ring is shifted to position B and released Find the speed of the ring when the spring attains its natural length.

A smooth ring 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 2m as shown below. At the instant ring and the block just starts sliding

A smooth ring of mass m can slide on a fixed horizontal rod. A string tied to the ring pases over a fixed pulley B and carries a block C of mass 2m as shown below. As the ring starts sliding

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(=2m) as shown in figure. At an instant the string between the ring and the pulley makes an angle theta with the rod. a. Show that, if the ring slides with a speed v, the block descends with speed v cos theta , b. With what acceleration will the ring starts moving if the system is released from rest with theta= 30^0
