HP Cycle 26

Today, we'll look at another lab in ↩️ Pivot Interactives called "Ballistic Simple Pendulum Challenge."  This is a classic physics problem which will give us the opportunity to think through the different problem solving methods we have learned in this class up until this point.  Traditionally, ballistic pendulums are used to measure the velocity of fast-moving projectiles such as bullets.  After making measurements using a model, we will explore the differences between the expected and actual results.  We'll have some time next class to finish this lab.

Today, we'll remember that momentum is a vector and discuss momentum problems in two-dimensions.  The discussion will brief and touch upon our previous experience with two-dimensional vectors.  We'll do the first problem from this Momentum 2-D presentation.  

Then, we'll do 📖 textbook collision problems: #35, 39, 63.  

Optional extra practice:  pages 2 and 3 in Momentum Packet.  (SOLUTIONS to Cons Momentum CompuSheet & SOLUTIONS to Momentum Practice Problems p 3)

Homework:  Finish all 📖 textbook problems up till this point.
