A billiard ball rolling across a table at [v1] m/s makes a head-on elastic collision with an identical ball. Find the speed of the first ball after the collision when the second ball is initially at rest. Express your answer in m/s.

A billiard ball rolling across a table at [v1] m/s makes a head-on elastic collision with an identical ball.Find the speed of the first ball after the collision when the second ball is moving toward the first at a speed of [v2] m/s. Express your answer in m/s.

A [m]-kg particle has a speed of [vA] m/s at point A and a kinetic energy of [KB] J at point B. What is its kinetic energy at A? Express your answer in J.
