Need to complete assignment 2-4 typed out and formatted. Number of pages is dependent on how long each question takes to type out. See attachment for assignment questions.

This week’s lab reinforced what you learned about radioactive decay. You were able to study a radioactive sample of rock to learn about types of decay, decay series, and half-life. You learned how to balance nuclear decay equations using nuclide notation and how to calculate the half-life of a radioisotope. Your knowledge of these concepts helped you identify the radioactive sample of rock you found after the meteor crashed to Earth.
When you are satisfied with your work in the lab, complete the Introduction to Radioactive Decay Lab Report.

Part 1: Motion with constant velocity
1. Through a web browser, navigate to http://phet.colorado.edu/en/simulation/moving-man and start the simulation. There are two tabs for this simulation, called “Introduction” and “Charts.” For today’s activity, you will need only the “Introduction” tab. Play with the controls of the simulation to get used to the controls.
2. Reset all of the man’s values to zero.
3. Using the position slider, set the man to stand near the tree. Give him a velocity of 1.2 m/s (and an
acceleration of 0).
4. Click to start the man in motion until he hits the wall, then hit to stop recording.
5. Use the playback feature to answer these questions.
