Aperson lowers a bucket into a well by turning the hand crank, as the drawing illustrates. the crank handle moves with a constant tangential speed of 1.22 m/s on its circular path. the rope holding the bucket unwinds without slipping on the barrel of the crank. find the linear speed with which the bucket moves down the well.

Explanation:

As we know that diameter of hand crank is given as

Also the diameter of the shaft on which the rope is wound is given as

now we know that both are moving with same angular speed

so we will have

so we will have

sonar - device which is used to find the submit submarines, sankalp ship. sonar waves consists of a transmitter and detector which are installed in the observation centre on board of a ship. the ultrasonic waves are sent into the sea at high frequency about 1000 khz in all direction.
