1) a .75 disk rolls down a 10m ramp. how many revolutions does it complete.
2) a uniform solid disk starts at 52 rad/s. to rest, it does 3900j of work. it has a radius of 1.2m. how long does it take to stop and how far does it go? (1/2mr^2)
3) a wheel is rotating at a constant rotational acceleration. what is true?
4) if you release a hoop, disk, and sphere at the same time from a ramp, what will have the greatest rotational acceleration.
5) 2 cylinders rotate counter clockwise are brought together. what is their rotational speed after? (one wheel has constants all of 1, the second one has constants all of 2)

4. now look at the green lines you created by connecting the three boiling point data points and the three melting point data points. for each of these lines, describe any trends you see. 5. locate the elements on your periodic table that you circled in green on your graph. what term or description would you use to identify these elements with respect to the periodic table? 7. using the room temperature line (orange line) and your periodic table, make lists that identify the state of matter (gas, liquid, or solid) in which each element you plotted exists at room temperature. explain your answers.

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
