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.
