A 20 gram bullet (m = 0.020 kg) moving at 700 m/s strikes a stationary block of mass M = 1 kg. The bullet comes to rest inside the block immediately, before the block has had time to slide. Once the block begins to slide, a 4 N frictional force opposes its motion. Through about how many meters will the block slide before coming to rest?
