Physics Applied to The Real World: The Female Canon

Jennifer Smith is known for her unconventional career path and upbringing. Commonly known as "The Canon Lady", Smith travels the world to be shot out of a real canon at county fairs, festivals, and amusement parks. This out of the ordinary practice isn't unknown to Smith. 

The proud projectile is a second generation cannonball to her father, Dave "Cannonball" Smith, a Guinness World Record holder. Her father's record holding practice influenced Jennifer, her older sister, and her brother to also become human projectiles. At just 13 years old, Smith demanded to be shot into the world of human projectiles, just like the rest of her family. 

As fun and entertaining The Canon Lady is as a circus performance or an attraction at a fair, extreme measurements of trajectory and projectile motion must be taken. Just a few degrees higher or lower than intended could be detrimental to Smith, causing her to land just a few feet shy of the safety net. 

So what does happen in an applied physics sense? Smith is a 1.57 meter projectile, being shot out of the cannon 18.29 meters in the air before landing in a 19 foot by 52 inch net 38.1 meters away. "In a split second, I go from standing still to flying in the air (Meet 'The Cannon Lady')."

Jennifer performing her very calculated stunt

The cannon Smith performs her stunt with is 8 meters long, and launched with a velocity of 19.44 m/s with a 40-45 degree angle in order to get the furthest range of projectile motion. Depending on the distance of the net in relation to the cannon, Smith has to set the cannon at an exact angle in order to land safely. 

Jennifer Smith's articulate measurements and calculations directly relate to lab's we have done, and seen for ourselves, in physics class. For us, the textbook in the 'Shoot to Win' lab is our 'safety net'. Just like Smith and other human cannonballs, we had to calculate where to put our 'safety net' in order for our projectile to land safely. The math and calculations we did in class are the same calculation's Smith does in order for her to know how to angle her cannon and place her safety net. 

Essentially, just as we had one chance to hit the textbook with the projectile, Smith also gets once chance to hit the safety net as a projectile.

The Physics of Spiderman

Over this past weekend after I finished working on my homework, I decided to relax and watch a few movies before going asleep. Among the movies I watched was Spider-Man 3 from 2007 and despite the movie flaws I was interested by the scenes that showed Spider Man shooting through the sky with the use of his webs that come out of his wrists. Due to this, I decided to make my blog post about the physics of Spider-Man's slingshot. After doing some research, I discovered just how much information there is on the physics of Spider-Man and how elements of Spider-Man can be used as examples for most topics learned in mechanics. For this investigation, I will not be using the horrible cliche and terrible CGI infested mess that Spider-Man 3 is but instead the all around superior Spider-Man movie of Spider-Man 2 to investigate the physics of Spider-Man's web propelled slingshot.  I want to talk about what happens in terms of physics when Spider-Man launches himself across a dista...

Physics of Sound Dampeners and Active Noise Cancellation

Physics of Sound Dampeners and Active Noise Cancellation Sound dampening foam panels in a recording studio. ANC headphones worn by pilots and/or passengers in consumer aviation aircraft.  Acoustic treatment of soundscapes has grown alongside the sound production industry. Whether through absorption panels, diffusors and cloud panels to treat a space or headphones placed directly over the ears of listeners, acoustic treatment comes in many forms. Environments are treated acoustically to absorb excess sound to prevent sound levels from crossing a threshold above which the desired goal cannot be had. Before getting into sound dampening, we must discuss sound. Sound is produced when an object vibrates (a form of oscillation) and temporarily displaces nearby air molecules causing a wave effect as the displaced molecules collide with their neighboring molecules. Sound waves are fluctuations in pressure as the initial displacement of molecules experiences collisions that in ...

Physics of Black Holes...Or Lack Thereof

Isabella Jacavone To comprehend how the universe works, we must dwell into the most basic building blocks of existence; matter, energy, space, and time. NASA's  Physics of the Cosmos program involves cosmology, astrophysics, and fundamental physics intended to answer questions about the elusiveness of complex concepts such as black holes, neutron stars, dark energy, and gravitational waves. In this blog post, I'd like to elaborate on a subject that is very intriguing  to me; Black holes. And more specifically, what would happen if we got near one. A black hole is anything but a hole, but rather an immense amount of matter compacted into an extremely small area. A black hole is caused when, hypothetically, a star four times more massive than our sun collapses into a sphere no bigger than 600 square km. To put that in perspective, that's about the size of New York City. B lack holes were predicted by Einstein's theory of general relativity, which showed that when a...
