Tutorial Section 7.4 - Experiment: collisions with different outcomes Initially, consider an experiment in which a glider collides with another glider of equal mass, which is initially at rest. Glider A will be the glider moving with constant velocity, while glider B is at rest. Both gliders have the same mass. System C is the system of glider A and glider B. Use photogate measurements to calculate the initial velocity of glider A, and the final velocities of the gliders. We will now determine the type of collision. photogate reading velocity momentum Glider A (initial) Glider B (initial) Glider A (final) Glider B (final a What is the change in momentum of System C? Is the final kinetic energy of system C different than its initial kinetic energy? If it is, where did the energy go? Is the collision elastic, inelastic, or neither? If it is inelastic, is it perfectly inelastic? Explain how you came to this conclusion. B. Now we will consider a collision between gliders that stick together. In the experiment, a glider will collide into the other, The pin will embed itself into the putty plug of the other glider and the two gliders will stick together. Glider A will be the glider moving with constant velocity. while glider B is the glider at rest. Both gliders have the same mass. System C is the system of glider A and glider B. Note, make sure the collision is between the pin and the plug, and not between anything else. Use a photogate to measure the initial velocity of glider A, and use a second photogate to measure the final velocity of the combined gliders. You might find it easier to remove the flag from glider B photogate reading velocity momentum Glider A (Initial) Glider B (initial) Glider B (final) 95 a What is the change in momentum of system C? b. Is the final kinetic energy of system C different than its initial kinetic energy? If not, where did the energy go? C. Is the collision elastic, inelastic, or neither? If it is inelastic, is it perfectly inelastic? Explain how you came to this conclusion
