In a police rifle test, a 15-g bullet traveling 213 m/s in avertical direction suddenly buries itself in a 2.4-kg block of woodat rest directly above it. As a result, the bullet-blockcombination moves vertically upward.
(a) Determine the velocity of the bullet-block combination justafter the impact.
(b) Determine the maximum height reached by the bullet/blockcombination.
(c) Is kinetic energy conserved in this collision? Â
