Perform the analysis for energy and momentum as before. using the quasi-analytical rotational inertia from the previous question, calculate the angular kinetic energy of the ball before the collision, and the angular kinetic energy of the pendulum system after the collision using equations 5, 6, and 11.  what is the kinetic energy of the ball immediately after the collision? why?  is this a perfectly elastic collision? what is the percentage of the kinetic energy lost (converted to thermal energy) during the collision?

Aray of light traveling parallel to the principal axis of a concave mirror will be reflected through the mirror's

Part 1: a magnetic levitation or maglev train rides rails without touching them. explain how this works using your data. include the appropriate magnet drawing in your answer. part 2: two objects are near a bar magnet. one is about 1 cm away, while the other is 6 cm away. compare and contrast the magnetic force that affects each object. use your data to answer the question

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix. b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds. c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer. d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.
