Find out the velocity of Block D

Find out the velocity of block B in a pulley block system as shown in figure.

Find out the velocity of block E as shown in figure.

A bead C can move freely on a horizontal rod. The bead is connected by blocks B and D by a string as shown in the figure. IF the velocity of B is v. find the velocity of block D.

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.
