8. You have been tasked with disposing of some radioactive waste from the manufacture of medical imaging agents. The main radioactive isotope in this waste is 131 I (which has a half-life of ~8.0 days and decays primarily via a β- mechanism). There are companies that specialize in the disposal of radioisotopes, but they are very expensive. The local landfill has agreed to allow you to dispose of the waste as long as the radioactivity is below 2 x 10-4...

Two cars of the same mass drive with the same speed of 60 miles per hour. They approach each other at an angle of 90 degrees. What is the speed (in miles per hour) of the two cars, after they undergo a completely inelastic collision and continue to move jointly into the 45 degrees direction? (Moving jointly into the 45 degrees direction means that after the collision the two cars move together into the direction right between the directions of...
