A player strikes a hockey puck giving it a velocity of 48.83 m/s. The puck slides across
the ice for 0.198 s after which time its velocity
is 46.83 m/s.
The acceleration of gravity is 9.8 m/s

.
If the mass of the puck is 185 g, what is the
average drag force exerted on it by the ice?

What is the coefficient of kinetic friction for
the puck sliding on ice?

If the puck strikes the goalie’s pads and stops
in a distance of 3.57 cm, what average force is
exerted on the pads?
Answer in units of N.

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.
