A 4.50 g} bullet is fired horizontally into a 1.10 kg} wooden block resting on a horizontal surface. The coefficient of kinetic friction between block and surface is 0.200. The bullet remains embedded in the block, which is observed to slide 0.200 m} along the surface before stopping.
Part AWhat was the initial speed of the bullet?v = m/s}
