A bullet with a mass of 5 gramsand speed of 560 m/sis fired horizontally atablock of wood with a mass of 2 kg. The block rests on a frictionless horizontal surface. The bullet hits and gets stuck in the block. which one of the following is correct?
A. Only momentum is conserved
B. Only kinetic energy is conserved
C. Neither momentum nor kinetic energy is conserved
D. Both, momentum and kinetic energy are conserved
Answers: 3
.
. After: 
. The secret is that other energy is in work of deformation forces (they in turn heat a bullet and a block).
