Remember that I will be at a conference on the 7th and 8th.
Tuesday, March 5: Here are answers to the introductory packet. Tuesday, students received a second worksheet called "More Parametric Concepts" which has more equations to graph and more parameters to eliminate and more connections to make about lines, circles, ellipses and hyperbolas. Here is a PDF with some answers to the problems. However, it isn't complete.
Wednesday, March 6: Here are the answers to the 3rd days worksheet.
Monday, March 11: We reviewed, answered questions and looked at projectile motion.
Tuesday, March 12: I postponed the quiz until Wednesday to the delight of some and disappointment of others. However, we looked into more detail at projectile motion and got a quiz review.
Wednesday, March 13: We took a quiz, determined if a bus could jump a 50 ft. span, and received a Review Worksheet that I pulled at the last minute when I realized that several students would be out for the next 2 days. The review worksheet is good and these should be the answers. However this is the assignment for tonight and the answers are correct, I believe. And, although it has answers, I think there are some other problems below that have also been worked out at some time or another.
II. Selected Problem worked: Problem #2
III. Another problem #1
IV. Another Problem #2
Thursday, March 14: Today we reviewed and decided that the test should be Monday!!!!!
Friday, March 15: Today we answered more questions and we were given the "Baseball Problem".
The Baseball Problem
An outfielder catches a fly ball 300 feet from home plate. The runner on third base is tagged up and will attempt to score. The relay man is midway between the outfielder and home plate. Provide a mathematical argument as to whether or not the outfielder should throw the ball to home with the assistance of the relay man. Be sure to list all assumptions being made in your analysis.
Assumptions:
- All throws will be accurate
- The relay man needs four tenths of a second to catch the ball from the outfielder and throw the ball to home plate
- There is no air resistance; therefore, the ball will travel the entire flight at the same speed.
- Both the outfielder and the relay man release the ball with an initial velocity of 100 feet per second.
- The outfielder and the relay man release the ball at a height of six feet off the ground.
- The ball reaches the relay man three feet off the ground and reaches home plate at ground level without a bounce.
