Two identical carts are set up to collide on a track in a physics classroom. Assume you may neglect friction between the carts and the track. Motion detectors are set up to measure the velocity of each cart both before and after the collision. The bumpers on the carts can be adjusted to change the elasticity of the collision. Three trials at different elasticity settings for the same initial velocities result in three different final conditions. In Trial A, the two carts come to rest as a result of the collision. In Trial B, the two carts bounce off each other and exchange velocities. In Trial C, the two carts bounce off each other and move with lower speeds than they had before the collision.
In a clear, coherent, paragraph-length response, identify the types of collisions associated with Trials A, B, and C. For each trial, describe the center-of-mass velocity before, during and after the collision. Also describe any energy changes during the interaction, clearly listing the objects in your system.

During physical science, ms. greene challenged her students to produce an energy transformation. james and jill wrapped a 4-inch nail with a coil of fifty turns of wire. they connected one end of the coil to one terminal of a knife switch. they connected the other terminal of the knife switch to the battery. finally, they connected the end of the coil to the other terminal of the battery. james held the tip of a 1-inch nail near the flat end of the 4-inch nail. jill closed the knife switch quickly and then opened it. the 1-inch nail was pulled toward the 4-inch nail. what is the best explanation of why the nail moved? a) electrical energy was converted to mechanical energy in the 1-inch nail. b) the 4-inch nail became an electromagnet and the magnetic force attracted the 1-inch nail. c) the electric current in the 4-inch nail was converted to mechanical energy in the 1-inch nail. d) the 4-inch nail had a positive charge and the 1-inch nail had a negative charge. opposites attracted.
