Blocks A and B have dimensions as shown ...

Blocks A and B have dimensions as shown in the fig. and their masses are 8 kg and 1 kg respectively. A small block C of mass 0.5 kg is placed on the top left corner of block A. All surfaces are smooth. A horizontal force F = 18 N is applied to the block B at time t = 0. At what time will the block C hit the ground surface? Take `g = 10 m//s^(2)`.
