In the adjacent figure, a uniform cube of mass `m` and edge `l=2m` is lying at rest an a rough horizontal surface. A small ball of mass `m` hits the cbe at its top edge with horizontal speed `v_(0)` and sticks to it. Friction is so large that the cube can rotate about the edge `'O'` without sliding. Calculate the minimum value of `v_(0)` ( in m/s) so that the cube will topple. Ignore any loss of energy due to friction at the edge `O` and take `sqrt(2)-1=  sics_images/RES_P20_16_MT_E01_048_Q01.png"
