Second Scribe of the Second Week of the Second second... There's something about that number I guess.

Helloooo... RICOLAAAAAAAAAAAAAAAAAAAAA!!! Just kidding, but I really just did have one. Not for the cough, but the lemon drops just taste good. Soothing for the throat too. Anyhow, as you all ladies and tangents have derived from the title, this is the second scribe post during the second week of school in the semester..and omigosh I just realized it's the second day of the week too!! [Is this an omen? .....]

Hopefully this scribe post will be up to par with the first. I'm going to attempt and probably fail explaining the main idea of what we did in class today. I'm probably a bit rusty on the concept of relative velocity itself, and what I remember is in bits and pieces...literally. I'll try my best.

We started class today by grabbing textbooks and turned to page 95. Ms. K briefly flipped through the pages we were assigned to read last week and summarized each part.

We examined three cases of relative motion involving realistic situations, such as a person swimming to the shore but also being swept by a current.

**IMPORTANT DETAIL: Drawing the correct diagrams and knowing the direction of the vectors is one of the most important things to know when dealing with calculating relative velocity. Knowing how to draw the diagram and the position of the measurements of velocities and locations of the angles helps you correctly find the vectors in the end.

Another section was determining the time it takes to cross, for example, a finish line in a race, utilizing velocity = distance over time formula. Its use in this context is one of the only times that formula is required in the unit.

AIRPLANES
The main thing we had to know is what TAILWIND and HEADWIND are.

Tailwind is the wind current that travels in the direction that the plane is going, making it easier for the plane to fly forwards because it helps it along. This current is the protagonist...our friend.

Headwind is the current travelling in the opposite direction of the plane, giving the plane difficulties and slowing it down. This current is the evil enemy.

Afterwards we corrected the majority of the sheet given to us yesterday, questions 34 to 41, but then we didn't quite finish correcting those. Tomorrow the class will conclude correcting the last two questions and possibly 38 if there is time.

But for now, here are the answers to what we got today.

34.a)
34.b)

35. 101.5 km/h, 98.5 km/h

36a) -35 km/h
b) +35 km/h
c) +125 km/h
d) +125 kmh

37) 20 degrees [S of E]

38 omit for now. no time -no crime.

39) a = 33 km/h [S]

40 and 41 will be finished tomorrow

I'm sorry for the rushed scribe. I would've done a better job if I got home earlier today. It's so "half-banana'd". But there's always the edit function and I can redeem myself. But I really need to get this other hw done. But for now, the next scribe is........... NICOLIASSSSSSSSSS!!!
