A block `A` of mass `10 kg` rests on a second block `B` of mass `8 kg`. The coefficients of friction at various surfaces are shown in figure. A horizontal force of `100 N` is applied on upper block at `t=0`. Determine the velocity of block `A` relative to block `B` after `0.01 s` of application of force. The system is initially at rest. Express your answer in `cm//s`. Take `g=10 m//s^(2)`.
