Day 13

Hi class,

The best way to prepare for the quiz tomorrow is to review your lecture notes and rework all the homework problems, especially problems 13-15 in section 2, problems 40 through 44 in section 3, and problems 4 and 9 on page 977.

For the students in fifth period, I have posted the answers to problems 40 through 44 in section 3 and problem 9 on page 977 below.

40)     a. 142.9 cm     b. 768 kg
41)     a. 2.7 X 10^3 cm     b. 2.12 X 10^7 cm
42)     a. 78 m^2     b. 12 m^2     c. 2.5 m^2     d. 81.1 m^2
43)     a. 2.0 m/s     b. 3.00 m/s     c. 2.00 m/s     d. 2.9 m/s
44)     5.3 g/cm^3

09)     5.99 %, 4.63 %, 3.81 %

GOOD LUCK!!!
