1/9 Physics class and homework due 1/16

Hi folks,

Today we used just about every concept we've learned this year and applied our knowledge to the game of Angry Birds. We discovered the impulse, velocity, momentum and more of the different objects in the Angry Birds world.  It was a very difficult challenge and folks really did a great job attacking the problems.

I've included the questions below in case you want to take a look at them.  Here's a great write up of a fellow who did the same kind of a thing we did today.  It's pretty interesting if you want to take a look.  By the way, he calculates the slingshot to be 5 meters tall!  

No recording this week since most of class was taken up by the activity.

Homework this week is a scavenger hunt.  I want you all to find two examples of all the concepts written below.  

Rules:

They must all be different.   

They must all be photos taken with a camera (not images from the internet).

They can be things that you just come across or you can set up situations that exemplify the concept.

Write a sentence for each one indicating why that photo is an example.

Videos are allowed if you wish.

You can print out the photos to hand in or you can email them to me.

1.  Newton's First Law

2.  Newton's Second Law

3.  Newton's Third Law

4.  Momentum

5.  Impulse

6.  Acceleration

7. Inertia

Angry Birds Analysis

Some assumptions for you:

The time it takes the rubber band to hurl a bird is .05 sec.  (This is the time of a pitch.)

The mass of the Red Bird is 6kg (the same as an eagle)

Gravity is normal 9.8 m/s2

Do # 8 first!!!!

1.  What is the maximum horizontal velocity of an Angry Bird?

2. What is the maximum vertical velocity of the Angry Bird?

3.  What is the maximum resulting velocity of the Bird?

4.  Are all birds the same mass?  How do you know?

5.  What is the force of the rubber band?

6.  What is the mass of a rock (be sure to describe what rock you're measuring)?

7.  What is the impulse on the angry bird when it's fired.

8.  What is the height of the sling shot?

9.  Does the Blue Bird conserve momentum when it splits?  How do you know?

10.  What's the momentum of the Red bird?

11.  Using Angry Birds give me one example of the following:

a) Newton's First Law

b) Newton's Second Law

c) Newton's Third Law
