A bullet of mass 0.25 kg is fired with velocity 302m/s into a block of wood of mass 37.5kg.It gets embedded into it. The block `m_(1)` is resting on a long block and the horizontal surface on which it is placed. The coefficient of friction between `m_(1)` and `m_(2)` is 0.5. Find the displacement of on and the common velocity of `m_(1)` and `m_(2)`. Mass `m^(2)`= 12.5kg.

Answer

`[0.2m,1.51 m//s]`
