A bullet of mass 7.00g is fired horizontally into a wooden block of mass 1.29kg resting on a horizontal surface. The coefficient of kinetic friction between block and surface is 0.250. The bullet remains embedded in the block, which is observed to slide a distance 0.270m along the surface before stopping. What was the initial speed of the bullet? Answer should be in m/s and show all work.
