The figure shows a bullet with mass of 0.159 kg moving horizontally toward a block of mass 1.54 kg that is at rest on a horizontal, frictionless table. The initial speed of the bullet is 348 m/s. The bullet embeds itself into the block and the bullet and block move together as one unit after the collision. 1) What is the speed (in m/s) of the bullet-block combination after the collision? If it took 2.55 ms for the bullet to change speed from 348 m/s to the final speed after impact, then
