A 60-g bullet is fired with a horizontal velocity of 260m/s and becomes embedded in block B which has a mass of 3kg. After the impact, block B slides on the 40-kg carrier C until it impacts the end of the carrier. Knowing the impact between B and C is perfectly plastic and the coefficient of kinetic friction between B and C is 2.0, determine (a) the velocity of the bullet and B after the first impact, (b) the final velocity of the carrier.
