A small block of mass `M` move on a frictionless surface of an inclimed from as down is figure . The engle of the inclime suddenly change from `60^(@)` to `30^(@)` at point `B` . The block is initally at rest at `A` Assume the collsion between the block and the incline are totally inclassic `(g = 10m//s^(2)`)

If collision between the block and the incline is completely elestic , then the vartical (apward) component of the of the block at point `B` immediatly after it stricess the scond indine is -

A

`sqrt30 m//s`

B

`sqrt15 m//s`

C

0

D

`-sqrt15 m//s`
