Maybe we solve it from the frame of upwards moving pulley and then equate velocities along the string.
I got an equation in terms of sin ϴ and cos ϴ and none of the options match with it. Maybe its wrong. I just used the usual, differentiating the length of rope equation.
Yes same equation.
Simplifying this gave me post #4
I don't know about the answer, but this method seems very correct to me.
Exactly ...got similar @Chirag_Hegde
