The car A is used to pull a load B with ...

The car A is used to pull a load `B` with the pulley arrangement shown. If A has a forwed pulley arraangement shown. If A has a forward velcotiy `v_(A)` determine an experssion for the upward velcotiy `v_(B)` of the load in terms of `V_(A)` and `theta, theta` is angle between string and horizontal
.

A

`(1)/(2) V_(A) cos theta`

B

`V_(A) sin theta`

C

`V_(A) cos theta`

D

`(1)/(2) V_(A) tan theta`

Text Solution

Verified by Experts

The correct Answer is:
A
Let `theta` angle between string and horizontal `T` is tension in string
`sum T.V =0, -T cos theta V_(A) + 2T V_(B) =0`
`V_(B) =(1)/(2) V_(A) cos theta`
