Block A is released from rest from wedge B. find out velocity of the wedge 'C' when the bloack A slide down completely after climbing up on it. All surfces are smooth. Block A, wedge B and wedge C are at rest initially. |

Answer» `sqrt(2gH)` `0=mv_(A)-2mv_(B)` `(1)/(2)2mv_(B)^(2)+(1)/(2)mv_(A)^(2)=MGH` When block A climbs up and then climbs down from C. By CONSERVATION of momentum and energy velocity of with `C=(2m)/(m+2m)V_(A)` |
