Accident Report2/2/2020 On January 17, 2018, an automobile accident occurred at the intersection of Furiosa Dr. and Fury Rd. in Joule, VA between a compact car (driven by Mike Rokar) and a tractor-trailer (driven by Lincoln Hawk). At this intersection, the truck driver had a flashing yellow light while the car driver had a flashing red light. Neither driver claims responsibility for the accident. The car driver, Mike Rokar, claims to have made a full stop at the light before entering the intersection and that Mr. Hawk did not slow down prior to the collision. The truck driver, Lincoln Hawk, claims to have been braking before the collision and that Mr. Rokar did not stop at the flashing red light. The court has asked my accident investigation agency to provide a comprehensive analysis of the collision from a physics perspective. My team has put together a formal report for the court that assesses the claims of both drivers and determines if one, or both, of the drivers is at fault. It is my conclusion that Mr. Lincoln Hawk is at fault for this accident due to his excess speed and failure to make a full stop at a flashing yellow light. Using forces and motion, work and energy, friction, the conservation of momentum, and kinematic equations I was able to figure this out. Momentum is the quantity of motion of a moving body, measured as a product of its mass and velocity. I used to conservation of momentum law to determine the initial speeds of both vehicles. This is because we can establish where the two vehicles collided and how far they traveled after the collision. By looking at how far they traveled after the collision, we can see how fast they were moving before the collision. This is because momentum is kept in the system. By using kinematic equations and accounting for the friction between the tires of the vehicles and the ground, I was able to rebuild what happened. Space Station11/1/2019
The Ballinger and Pelson Space Station is the first of its kind: an economically advantageous space investment and travel destination. It offers civilians the opportunity to travel to space and have a resort-like experience, and offers private sector business the chance to tap into this market. Interest in space by the masses has been rekindled by the spectacle of private sector space companies like SpaceX or Blue Origin. Space travel has also become the cheapest it has ever been. As a result of both of these factors, there is now an opportunity to send a large amount of people to space for a relatively low cost. Our space station will serve as the only destination in space, taking in the large flow of people and supplying businesses with them. We will not be like other stations and pursue scientific innovation due to the sheer number of stations dedicated to that and the lack of demand for it.
The space station will orbit at 300 miles (482,803 meters) above the Earth. This is about 80 miles above the international space station (ISS). We are able to put it higher because we do not have to worry about the capabilities and fuel levels of refueling/resupplying missions (the ISS had to consider the Progress and Soyuz capabilities as well as the space shuttle capabilities). We are also still below the Van Allen belts (311 miles or 500,000 meters), so we do not have to worry about increased radiation. The space station will have a tangential speed of 7,272.54 meters per second, and an angular speed of 3.078 meters per second. The space station will be 1,498.1 meters by 100 meters and will use 2,996,200 kilograms of materials.
Introduction to Forces9/25/2019 Forces push and pull, trying to affect motion. They can be either from a physical source – the force applied by pushing something would be an example of this – or from a field – Earth's gravity would be an example of this. Forces are measured in newtons, or N. Mass is the unit of measurement for inertia. In other words, mass is a measure to an objects resistance to acceleration when a net force is applied. Its unit is kilograms, and should not be confused with weight, which measures the forces acting on an object – the most common example being the force of gravity on an object giving us its weight. Mass is closely related to inertia, because inertia is calculated using both the mass of an object and the speed. A vector is an object that has both direction and magnitude, like force or velocity. The opposite of a vector is a scalar, which has only magnitude. An example of a scalar would be speed or distance.
