Consider a scenario in which the flywheel described in part (a) (r1 = 1.7 m, mass m1 = 19 kg, v = 55 m/s at the rim) is spinning freely at its maximum speed, when a second flywheel of radius r2 = 2.1 m and mass m2 = 29 kg is coaxially dropped from rest onto it and sticks to it, so that they then rotate together as a single body. calculate the energy, in joules, that is now stored in the wheel.

Listed following are various physical situations that describe how light interacts with matter. match these to the appropriate category. 1) transmission? -visible light meets clear glass -visible light does not pass through a black wall -red light hits a red sweatshirt -light comes from your computer screen -cell phone signals pass through walls -blue light hits a red sweatshirt -white light hits a white piece of paper -light comes from a light bulb
