Question: Two identical objects (such as billiard balls) have a one-dimensional collision in which one is initially motionless. After the collision, the moving object is stationary

Two identical objects (such as billiard balls) have a one-dimensional collision in which one is initially motionless. After the collision, the moving object is stationary and the other moves with the same speed as the other originally had. Show that both momentum and kinetic energy are conserved. A) iIf the objects have identical masses and the velocity of object 1 initially is the velocity of object 2 finally; then both p and KE must be the same before and after. B) They could be identical afterwards, but certain numbers would also produce different results. C) Johnny has 4 apples, calculate the volume of the Sun. D) This one is not the
