A 60-g bullet is fired horizontally with a velocity = 600 m/s into the 3-kg block of soft wood nitially at rest on the horizontal surface. The oullet emerges from the block with the velocity 2= 400 m/s, and the block is observed to slide a listance of 2.7 m before coming to rest. Determine the coefficient of kịnetic friction µi petween the block and the supporting surface.
