3. Suppose a comet that is speeding through space hits a stationary asteroid. If we assume that neither object changes its shape or temperature but both change their direction and speed, the energy conversion during this collision is: (Hint: assume that these two objects act like billiard balls when one hits the other)
A) kinetic energy to kinetic energy
B) kinetic energy to potential energy
C) kinetic energy into sensible heat
D) kinetic energy into latent heat due to the flash boiling of the asteroid
E) potential energy to potential energy"
