A block 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 :

A

v

B

`(v)/(sin theta)`

C

`v sin theta`

D

`(v)/(cos theta)~

Text Solution

Verified by Experts

The correct Answer is:
B
`U cos ((pi)/(2)-theta)=v`
`therefore U=(v)/(sin theta)`

A wedge of mass M = 2m rests on a smooth horizontal plane. A small block of mass m rests over it at left end A as shown in figure. A sharp impulse is applied on the block, due to which it starts moving to the right with velocity v_(0) = 6 ms^(-1) . At highest point of its trajectory, the block collides with a particle of same mass m moving vertically downwards with velocity v = 2 ms^(-1) and gets stuck with it.
