34. Visit or call a bowling alley. Find out the "weight" of a bowling pin. Convert the "weight" of the pin to "mass" (use page 698 of your book to help you with this). Upon doing this, convert the "weight" of a 10 pound bowling ball to "mass." If you throw this 10 pound bowling ball at a rate of 10 meters per second towards the bowling pin calculate the total momentum of the "system" (bowling ball and bowling pin) before collision and after collision 15 points

"B" layer assignments (Choose one only)

35. Videotape a "demonstration" of momentum (this can be you and your friends or you videotaping something "happening"). After the demonstration, explain (do this on camera) how the Law of Conservation of Momentum is demonstrated. Creativity + Job-well done= possible extra credit??? 11 points

36. Design an experiment that demonstrates how to calculate the Potential energy of a ball dropped from a certain height 11 points

37. Design an obstacle course. Using only a meter stick, guide the bowling ball and tennis ball through the obstacle course. Calculate the speed, velocity, acceleration, and momentum of both the tennis ball and bowling ball. Submit your data to Mr. Wilson. Below your data, answer the following question: why is guiding the bowling ball through the obstacle course so much more difficult than with a tennis ball? Use the terms "inertia" and "momentum" in answering this question 11 pts A Layer Assignment (choose 1 only) 11 pts

(For a chance at full credit on "A" layer assignmentsà You MUST submit the following ) 1. Answer to the question (if a question is asked) 2. video presentation (2-5 minutes minimum) 3. 3 articles you research (actual articles need to be submitted/ NOT the websites) 4. A summary for each article *each summary needs 2 paragraphs paragraph #1: 8-10 sentences summarizing the article paragraph #2: 6-10 sentences stating your opinion of the article (did you like/dislike it/agree/disagree with it? critically evaluate the topic in this paragraph)

38. Are roller coasters safe? Conduct research to defend your opinion. Use Acceleration, momentum, and speed in your video presentation. Creativity + Job well done= Possible extra credit??? 11pts

39. . Research and evaluate(come up with your solution) to the "Traffic" problem on Interstate 75 Essentially, cars between 3:30 p.m. and 6:30 p.m. are constantly in traffic jams (i.e. waiting in 30 minute due to the way Interstate 75 was designed. In your evaluation include the "speed/velocity/momentum/acceleration" of trucks and why building a separate lane for truckers only is one solution to the problem that has been brought to the forefront. Is there another solution to the problem? Evaluate the problem through research.
