A lift is moving upwards with a constant speed of `5(m)/(s)`. The speed of one of the pulleys is `5(m)/(s)` as shown. Then the speed of second pulley is:

A

`5(m)/(s)`

B

zero

C

`7.5(m)/(s)`

D

`10(m)/(s)`

Text Solution

Verified by Experts

The correct Answer is:
A
In the frame of the lift first pulley will be stationary so velocity of second pulley will be zero and so in the frame of ground it moves with `5(m)/(s)`.
