A 0.0220 kg bullet moving horizontally at 450 m/s embeds itself into an initially stationary 0.500 kg block.
(a) What is their velocity just after the collision?
(b) The bullet-embedded block slides 8.0 m on a horizontal surface with a 0.30 kinetic coefficient of friction. Now what is its velocity?
(c) The bullet-embedded block now strikes and sticks to a stationary 2.00 kg block. How far does this combination travel before stopping?
