Physical Science A

Bellwork:
    1.  Working with you partner, I would like you to discuss the topics of:
                a.  Reflection
                b.  Refraction
                c.  Interference
                d.  diffraction
        -for each concept, describe what happens with the waves, provide 2 examples for each and             make one "quiz" questions for each of the topics. 

Check and discuss section one review questions.

Discuss Sound

HW:  Please answer the section 2 and 4 review questions on pages 332 and 343.

The test over this material will be on Wed.  We will go over the homework tomorrow, finish any material on sound and take a short practice test.

Physics A

Bellwork:
    1. A 3.0 kg fish is swimming at 1.5 m/s to the right. It swallows a 0.25 kg fish swimming to the left at     4.0 m/s. What is the velocity of the larger fish immediately after lunch?

    2.  A 3 kg mass is moving with an initial velocity vi. The mass collides with a 5 kg mass m2, which is     initially at rest. Find the final velocity of the masses after the collision if it is perfectly inelastic.

    3.  A hefty man of mass 150 kg jumps from a bridge onto a boat of mass 400 kg that is moving up        river at a speed of 5 m/s. How fast is the boat moving afterwards?

Collect the final explanations for the egg drop project. 

Test Projects.  Hopefully, we won't have to clean up any broken eggs.

As a class we will collect the data for the conservation of momentum lab.  Please finish the summary questions for homework.

HW:  Begin to study for our quiz we will have on Wed.  over momentum, impulse, conservation of momentum, and angular momentum.  Finish the lab questions.
