pulleys

[south apex]

The question asks to find velocity of B. I tried using the property that sum of velocities of strings is half the velocity of the pulley, but it isn't working. I got 10m/s and the answer given is 2m/s. Thanks.

try using this
$$\sum \vec{T} \cdot \vec{v} = 0$$
cuz its complicated asf

now its about equating forces and shit

mera 14/3 aarha hai 😭

last pulley ke middle wale string me tension nahi hogi?

[south apex]

Q6, sorry for the inconvenience

[south apex]

What is T?

[twilit rampart]

Tension

Oh, I haven't learnt about that yet, is it part of constraint motion? This question is from a pdf of pulley problems, I was able to solve other ones using the moving pulley relation

[twilit rampart]

It means sum of all internal forces is zero and applying this for different strings you’ll get equations and on solving them you will fetch relation between velocities

tension force nhi pdha ?

Thank you!

Nahin, I'll learn about it today
