The figure shows a bullet with mass of 0.152 kg moving horizontally toward a block of mass 1.25 kg that is at rest on a horizontal, frictionless table. The initial speed of the bullet is 256 m/s. The bullet embeds itself into the block and the bullet and block move together as one unit after the collision.   A: If it took 3.44 ms for the bullet to change speed from 256 m/s to the final speed after impact, then what was the magnitude of the average force (in N) exerted by the block on the bullet during this time?
