If the blocks are connected as shown in fig, the relation between their velocities is |
Answer» SOLUTION :The length of the string is  `L=2sqrt(d^(2)+y^(2))+x` Since, L is constant, DIFFERENTIATING with respect to tiem t, we get `(DL)/(dt)=(2xx2y)/(2(d^(2)+y^(2))^((1)/(2)))((dx)/(dt))+(dx)/(dt)=0` `rArr 2v_(1)cos theta + v_(2)= 0, v_(2)=-2v_(1)cos theta` |
