Chapter 3.3, Problem 2aT
A. Suppose that glider D is free to move and glider C rebounds.
1. In the spaces provided, draw separate free-body diagrams for each glider and for thesystem of the two gliders, system S, at an instant during the collision.
Which forces in your free-body diagrams for glider C and glider D do not have corresponding forces on the free-body diagram for system S?
2. The momentum of a system containing multiple objects can be defined to be the sum of the momenta of the constituent objects.
Use this definition to write an expression for the change in momentum of system S in terms of the change in momentum of glider C and of glider D.
3. Does the momentum of each of the following change during the collision? Explain how you can tell.
• glider C
• glider D
• system S
Are your answers consistent with your free-body diagrams and the direction of the net force in each case? If not, resolve any inconsistencies.
4. How, if at all, would your answer about the change in momentum of system S differ if glider D were replaced by a much more massive glider? Explain.

In the following figure, mass 1 slides down the frictionless ramp and undergoes an elastic collision with mass 2, which is initially at rest. Given all of the values shown in the image:
a) How far from the table does mass 2 land following the collision?
b) Following the collision, does mass 1 slide back up the ramp or does it continue off the table?
i) If it goes back up the ramp, determine the height that it slides back up to.
or
ii) If it flies off the table, determine how far away from the table mass 1 lands.
Given two balls, each of mass m, traveling together at speed v, what is the total linear momentum of this two-ball system? What is the total kinetic energy?
B.If the balls from the previous question strike three stationary balls (as in your previous tests), what is the total linear momentum of the ball(s) that are in motion after the collision? What is the total kinetic energy?
C. Is it possible for two balls (mass m each, speed v) to strike a line of balls and have a single ball (mass m) “scatter” from the other end of the line with twice the speed (speed 2v)? What would be the momentum of the single ball? What would its kinetic energy be?
a.) If an object is already moving and you applied another force parallel to it and with the same direction, does this mean that another counter force will be generated? Explain.
b.) Considering question (a), what if you applied a force lower than the force of momentum (and gravity, etc.) on the object, will it generate a counter force? Explain.
c.) On our activity, pushing the object at rest generates a counter force. How is this?
