2. Book 5.1.1 page 378: Read the Historical Feature; CV: 7, 8; E: 1 – 80, 81, 82, 85, 86 (change 86 from 100 square yards to 1000 square yards)
3. Book 5.1.2 page 378: 88, 98, 89, 90, 91, 92, 94, 103, 95, 96, 100, 102
94b. The latitude of Kingston is 35.880N and an axis distance of about 3414 miles. What is the linear speed of the Earth surface in Kingston?
Compare this answer to the answers from problems 93 and 94.
Make a conjecture about the linear speed of an object and the distance the object is from the equator. Image being at the exact spot of the North Pole. What would be your linear speed? What is your body doing?
Now image taking one giant step forward. Your linear speed has changed, but it’s very small, about 0.005 miles per hour. What is your body doing?
102b. Crossville is 35 miles west of Kingston. If the sun rises at 5:32 am in Kingston one morning, what time does it rise in Crossville on the same morning? Be careful with the time zones. By the way, the same approach would be used for the sun setting in the evening.
