Question
A black is dragged on a smooth plane with the help of a rope which moves with a velocity v as shown in figure. The horizontal velocity of the block is :
Options
A.v
B.
C.v sin θ
D.
Solution
x2 = y2 + d2
⇒ 2x
= 2y 
⇒
OR
Compoment of velocity along string must same so
vM cos θ (90 - θ) = v ⇒ vM =
