: I wish ALL of you could have known Mr. Hildebrand. His family came up and saw this Saturday. It meant so much to them. Please at least sign it or maybe write a note if you knew Greg.

: NNow the other wall is beginning to fill up.

: Type 1 Projectile Motion.

: . . .

: You can actually study weather on other planets as you career. Just ask Dr. Susan Pastacko.

: Something like 10 of the last 12 years have been the hottest on record.

: Rainbow

: 6.3.3b

: 6.3.7: Crazy Joe jumps the river.

: . . .

: no short cuts for type IIB, but the blue quad is usually involved.

: Selfie! with problem 6.4.3

: 6.4.4

: 6.4.4

: . . .

: . . .

: Type 1 kind of graphs

: Type IIA kind of graphs

: Type IIB kind of graphs.

: . . .

: yikes. Silent but deadly.

: ha!

: We used the Range Equation to solve for

: Our data from the first part of the Projectile motion lab. Here we used the Range Equation to determine the initial velocity of the black marble. Pretty consistent data. We double checked some of these numbers with our photogate and very accurate (±0.0001 seconds) timer.

: converting the diameter of the black marble from cm to ft.

: the equation we used in the lab to predict ∆x for the black marble.

: It is always best when you come to me with your work when you show me all the steps. Much easier to find where you veered wrong.

: Projectile Motion Lab

: . . .

: Be aware that there is a final step on this problem involving Pythagorean’s Theorem.

: Crazy Joe’s 57 Chevy goes off a cliff.

: . . .

: . . .

: One of the parts of the Crazy Joe problem that most students miss. The angle of the projectile motion is NEGATIVE which makes the sine of that angle NEGATIVE.

: If Saturn’s Rings were around Earth.
