- Each sheet has the same questions on it but each sheet has a different set of numbers.
- Every person should solve their questions but work together. Three person teams are to do sheets A, B, and C. Two person teams are to do sheets D and E.
- Keep all of your decimals.
- To check your answers, add up everyone’s answer to everyone’s number 1. Write it down.
- To check your answers, add up everyone’s answer to everyone’s number 2. Write it down.
- To check your answers, add up everyone’s answer to everyone’s number 3. Write it down.
- To check your answers, add up everyone’s answer to everyone’s number 4. Write it down.
- To check your answers, add up everyone’s answer to everyone’s number 5. Write it down.
- Enter your sums for each question on the Quia Quiz here. When answering the Quia questions, Answer to 3 significant figures. You will not need a username, password or secret word to take the Quia quizzes. These quizzes have unlimited retakes.
- 3 person teams go here: http://www.quia.com/quiz/4162622.html
- 2 person teams go here: http://www.quia.com/quiz/4162637.html
- If you got any sums wrong, work together to find the mistake, correct it, and redo the quiz. When you get a perfect score on the quiz quiz, show it to the teacher.
- You are expected to work only within your team. DO NOT WORK WITH OTHER TEAMS unless directed to.
What to do when the answer(s) in Quia are wrong.
- Check that everyone is doing the correct sheets.
- Check that you rounded properly.
- Check that everyone kept all the decimal places IN EVERY STEP.
- Check that the numbers in the formula are correct.
- Check with your teammates to see if the givens and/or setup is correct.
- Swap papers and check each other's math.
- Hmmm. Everyone has done something else wrong. Now is the time to seek help from a group that has finished. If none of the groups have finished yet, seek the teacher's help.

A 21.0 gram toy plane is launched from a special launcher that consists of a handle and a stick with a spring wrapped around it. The plane is pushed down until the spring reaches its maximum compression of 15.0 cm from the equilibrium position. What is the speed of the plane when it is 1.0 m above the spring's equalibrium position if the spring's spring constant is 200.0 N/m? |
