In the arrangement shown, wedge B B is at rest and block A A is moving towards the wedge. The surface between the block/wedge and ground is smooth, but the surface between the block and wedge is rough. After achieving 1-meter height on the wedge, the block stops with respect to the wedge due to friction. Then, in the process, ____________ . \text{\_\_\_\_\_\_\_\_\_\_\_\_}.

work done by the friction on the block is − 32 J -32\text{ J} work done by the friction on the wedge is 6 J 6\text{ J} total work done by the friction on the block is − 14 J -14\text{ J} work done by normal on the wedge is 0
