Hey y'all, Chris, a student at Cornell, wakes up at 8:59am for his 9:05 class. If the class is 1.5 km away, at what constant velocity does he need to travel in order to make it to class at 9:05? Neglect air resistance.

Ethan you're the man. Keep studying hard!

You can do it Mady!

This launch was nearly identical to our third launch, except we remembered to take screenshots. Pre-Launch Design Release Team Name: StackBNimble Corp.

This past Friday at Arts Fest, we brought Kerbal Space Program into the real world. Every year at Arts Fest, the Physics 1 students are given a project in which they need to construct a rocket out of a 2 Liter bottle, which is then launched on the track. If the rocket is in the air for at least 7 seconds, full points are awarded. This year, Mr. Fullerton gave all of his Physics C students the same project. If our rocket remained in the air for at least 7 seconds, then our reward would be 100,000 kerbency for our team in Kerbal Space Program. Our team, Stack B Nimble Corp., received the full re

I've never heard of Cherenkov Radiation before. Very cool!

Looks painful!

A couple days ago, a Swiss skier named Andri Ragettli landed the first ever 'Quad Cork 1800', in which he flew 38 yards off of a jump in Italy, making five full rotations and four head-under-body spins. The video of the jump is attached below. The true difficulty of landing such a trick is very clear when considering the physics behind it. First, in order to be in the air long enough to perform such a trick, a skier needs to gain a great amount of kinetic energy as he descends from the top of the hill. In order to do this, the height of the top of the hill should be maximized so as to maximize

I have played the saxophone for a very long time and really enjoy it. Although I have played it for so long, I have never learned the physics behind how blowing on a little piece of wood generates sound. In making a sound on the saxophone, one blows air at a high pressure through the mouthpiece. The reed controls the air flow through the instrument and acts like an oscillating valve. The reed, in cooperation with the resonances in the air in the instrument, produces an oscillating component of both flow and pressure. Once the air vibrates, some of the energy is radiated as sound out of the bel

Recently in my BC Calc class, we've been talking about series and in some cases the application of them. The harmonic series is especially applicable to music: in music, strings of the same material, diameter, and tension whose lengths form a harmonic series produce harmonic tones. Another application of the harmonic series is the Leaning Tire of Lire, a theoretical structure. Suppose that an unlimited identical books are stacked on the edge of a table in such a way that the maximize the overhang. In order to maximize overhang but prevent the structure from collapsing, we can apply the formula

That's so cool, that touch screens act like capacitors
