         If you had a basketball that was filled with mercury, about how much would it weigh? The density of mercury is
         13.6 grams per cubic centimeter. Hint: If you do not know the dimensions of a basketball, you should ESTIMATE
         them.

         2.
         A boxing match occured on a December day that the temperature was 32 degrees, but the
         announcers reported that heat would be a problem. Explain why this might be the case.




         3.
         A professor overheard a bar conversation between two Texans (true
         story). One claimed that the 1990 Formula 350 Firebird had a bigger
         engine than the 1995 5.7 L Trans Am Firebird because "back then"
         they didn't have to worry about fuel economy. The other argued that
         Pontiac increased the size from 350 cubic inches to 5.7 L in response to
         high sales of the 5.0 L Ford Mustang. Who is right? Do a calculation
         before you answer and bring your calculation to class.

            The Formula 350 has a bigger engine.

            The 5.7 L Trans Am has a bigger engine.

            It is impossible to compare the two engines given the information given.

            The engines in the two cars are identical.

            People should not drive cars with such big engines.

         Below is a space for your thoughts, including general comments about today's assignment. What was hard or
         confusing (or cool)? What would you like to spend extra time on in class? Do you see how this subject fits in with the
         others we have discussed?
