2. A 60-g bullet is fired horizontally with a velocity v, = 600m/s into the 3-kg block of soft wood initially at rest on the horizontal surface. The bullet emerges from the block with the velocity v2 = 400 m/s, and the block is observed to slide a distance of 2.70 m before coming to rest. Determine the coefficient of kinetic friction between the block and the supporting surface. 3 kg 400 m/s 600 m/s 60 g 2.70 m
