The three block shown in fig. move with ...

The three block shown in fig. move with constant velocities. Find the velocity of blocks A and B. given `V_(P2)=10ms^(-1) darr, V_(C)=2ms^(-1) uarr`.

Text Solution

Verified by Experts

`v_(A)=v_(p_2)=10 ms^(-1)`
Using shortcut method
For pulley `P_(2)`
`v_(P2)=(V_(B)+(_V_(C)))/(2)`
`10=(V_(B)-2)/(2) implies v_(B)=22 ms^(-1)`.
