THIS WEEK (my best guess):

Mon- Discuss Week ahead; Slide show; JM; HO 3.7 (Girl in Jeep) Worked on GIJ scenarios.

Tues- ROCKETRY MEETING #3; Worked on a really complicated GIJ scenario; Began discussing the beginning of Calculus. ACT Math Study Session: 6:30 – 8:30PM

Wed- I’ll be gone. The classes will work on the Dragster sheet and if you have time, you can work on the Girl in the Jeep; HO side 1 and 2 of Take Home Test #3; ACT Science Reasoning Study Session: 6:30 -8:30PM

Thur- GUEST SPEAKER: PETROLEUM GEOLOGY MEETING #2 (& PIZZA!); Girl in the Jeep due by 4:30PM; Discuss derivatives and power rule and work on the problems on 3.8 (Derivatives); HO 3.9 assign homework; MOVIE NIGHT!! (Moon)

Fri- Will wrap up 3.9; HO THT#3 (sides 3&4); FBF

LAST WEEK:

Mon- Discuss Week ahead; Slide show; JM; HO 3.4 (Video Questions); Continue deriving Orange Equations

Tues- ROCKETRY MEETING #2; Sign up for both upcoming Petroleum Geology Meetings; HO 3.5 Begin working problems and assign homework

Wed- PSAT! so . . . we will work a little bit, but the morning classes are at least half empty so we will spend most of the time watching the first part of “The Right Stuff” — the part about Chuck Yeager and breaking the sound barrier for the first time.

Thur- GUEST SPEAKER: PETROLEUM GEOLOGY MEETING #1; Worked on 3.5 Homecoming Parade and bonfire this night

Fri- Did Blue Day. Finished up 3.5. Sheet 3.4 (Video Questions) due at 4:30PM

: Our moon through it’s cycle.

: This is what I mean by showing work.

: This is what I thought I would get for an answer . . .

: . . . but was pleasantly surprised by this correct interpretation.

: NHS Basketball doing suicide drills in preparation for the season. Our own Jordan is already looking in season form.

: Someone abandoned this puppy on my neighbors back porch. Anyone want a puppy?

: !st Orange Kinematic Equation derived very easily from linear graph of v vs. t.

: 2nd Orange Kinematic Equation derivation (1st 6 steps)

: Last few steps of 1st Orange Kinematic Equation derivation

: First 5 steps of 3rd Orange Kinematic Equation derivation.

: 6th step of 3rd Orange Kinematic derivation.

: The key to the elegant derivation (8th step) of 3rd Orange Kinematic Equation derivation. I, unfortunately, didn’t take a picture of the other board which shows the last couple of steps, but you can find it on HUW sheet 9.

: Norman Advanced Robotics fall preseason work is well underway. Our in house contest will be the week before Thanksgiving.

: . . .

: . . .

: . . .

: Stephen comes back to help when he can.

: Michael is one of the leaders.

: . . .

: Sheet 3.5 problem #1 — Crazy Joe and the snake.

: 3.5.2 — The Gold Standard approach to Unit Analysis.

: 3.5.4

: mach 1.

: Our new Constants page at the back of the notebook.

: Air pressure has a lot to do with the speed of sound. Rule of thumb . . . the higher the density of the medium , the fast the sound wave moves through it.

: Sound waves move slower at the top of Mt. Everest than they do at sea level.

: Sonic Boom occurs when the sound barrier is broken through.

: When compression wave gets to the person on the grounds ear, they hear the sonic boom. It is a little like a wake behind a boat. We can treat the atmosphere as a fluid in this extreme case.

: Thunder is basically the concussion wave hitting your ears from the point where the lightning occurred.

: Depending on depth, sound waves in water are around Mach 3 or Mach 4. Dolphins will have this advantage when they get tired of our crap and take over the earth. Sound waves move through sandstone at around Mach 5, Some limestones at Mach 7, granite at Mach 18!

: Some good student work on 3.5.3

: good board work

: good board work

: good board work

: good board work

: good board work

: Kind of interesting.

: 3.5.5

: 3.5.5

: 3.5.5 This is really cool, you can determine the exit speed (muzzle velocity) of the bullet from finding the area of the average acceleration vs. time graph.

: 3.5.5 And you can find the length of the barrel from finding the area under the “curve” (essentially the area of the triangle in this case) in the v vs. t linear graph.

: 3.5.5 This is making the crazy assumption that a trio can be used to represent a bullet accelerating in a barrel.

: 3.5.5 Horizontal acceleration of the bullet is zero (assuming air drag is low) as it exits the barrel since the expanding gas that caused the acceleration is no longer under pressure.

: Initial acceleration of the bullet is zero. The front loaded curve is more logical than a flat a vs. t. This would mean that the bullet probably experiences a “crackle”. Wow!
