The Collision Theory Gizmo allows you to experiment with several factors that affect the rate at which reactants are transformed into products in a chemical reaction. You will need blue, green, and orange markers or colored pencils for the first part of this activity. 1. Look at the key at the bottom of the SIMULATION pane.

Answer: D. In any collision, there are always four quantities which are the same for both objects involved in the collision. Each object experiences the same force (Newton's third law) for the same amount of time, leading to the same impulse, and subsequently the same momentum change.
Solution: The momentum of the moving particle can be resolved into two components: that along the line of collision and that perpendicular to it. All of the momentum along the line of
collision, the 6 kg mass moves at a speed of 2 m/s. a) Find the final speed of the 4–kg mass. b) Is this collision elastic, inelastic, or something in between?
If the catcher's hand is in a relaxed state at the time of the collision, it can be assumed that no net external force exists and the law of momentum conservation applies to the baseball-catcher's mitt collision.

2 (a) The cue ball’s velocity is virtually the same as the black, but on a downward 45° trajectory. It is highly likely to enter the bottom corner pocket. (b) Kinetic energy is conserved, so it is an elastic collision. 3 v imp = 1.1 109 m s–1; this is faster than the speed of light. 4 Students’ own answers. For example:
