A bullet of mass 20 g moving at 400 m/s strikes a block of wood of mass 3.5kg initially at rest. The bullet sticks into the block and the two move off together on a horizontal surface, where a frictional retarding force of 4N is acting between the block and surface.

(i) Determine the initial common velocity of bullet and wooden block.

(ii) What distance does the block move before coming to rest?
