Question

An artillery shell explodes in midair and breaks up into many fragments. Which of the following statements are true regarding conditions immediately before and immediately after the explosion:I. The total momentum of the fragments is equal to the original momentum of the shell.II. The total kinetic energy of the fragments is equal to the original kinetic energy of the shell.Select one:A. Neither statement is trueB. Both Statement I and Statement IIC. Statement II onlyD. Statement I only

Answer 1

Explosion is inelastic.

So momentum is conserved in this explosion but kinetic energy is not conserved.

Hence, the option D is correct , statement I only.
