6. Two air hockey pucks are approaching each other as indicated below. Only the forces between the pucks are significant during the collision. Puck 1 has a mass m1 and initial speed |v:], while puck 2 has a mass m2. After the collision, the pucks are moving as shown below. a. Determine the initial speed of puck 2, in terms of variables in given in the problem statement. Justify your answer in words and/or equations. b. What is the relationship between the final speeds of the pucks? Justify your answer in words and/or equations. c. Determine the kinetic energy of a system that includes both pucks before the collision.
