1. Physics II 10/7
Suppose you made a graph of “Applied Force vs. Pull Distance” for the trebuchet on the right. What would the graph look like for trebuchet positions between θ =0° and θ =180°? [Assume that the pull distance is measured along an arcing path.]
What if you graphed “Energy required to pull back trebuchet vs. Pull Distance?” What would that graph look like?

2. Physics 10/7 Today: Friday: Complete launcher activities.
Check & Review Problems. Do you need more practice problems??? If so, which kind – similar to which numbers??
Work Time
Friday: Complete launcher activities.
Tuesday: Accuracy Competition.
Thursday: Test.
In-class portion on Thursday, same content as practice questions. Allowed materials: calculator, paper, pen/pencil.
Take-home Excel portion assigned Thursday, due the following Friday. If you know how to set up all of the spreadsheets we have already done – by yourself – you should be prepared. Allowed materials: anything but another living person.
