39. (a) Momentum of the bullet-block system is conserved
in the collision, so you can relate the speed of the block
and bullet immediately after the collision to the initial
speed of the bullet. Then, you can use conservation of
mechanical energy for the bullet-block-Earth system
to relate the speed after the collision to the maximum
height. (b) 521 m/s upward
