In class we utilized the Logger Pro 3.6.1 in order to have an analysis of a mini cooper car crash. We inserted the video and inputted a measurement of 2.46 m from the center of the wheel to the other center of the wheel to create a frame of the object. Then we selected a point behind the dummy’s (passenger) head in order to graph its velocity, position, and acceleration during the crash.
Once we set the frame and the point we kept clicking the same point of the frame as the video keeps playing during the crash. The points plotted an upper position graph and lower velocity graph. Once you have the graph plotted you can find the acceleration, velocity, and position of the dummy during the car crash. The highlighted section of the graph shows the motion of the passenger during the crash. The boxes that have a line dragged to the section say the velocity and acceleration. Acceleration was found because the slope of the velocity graph gives the acceleration. The slope of the position gives the velocity and we checked the precision of the velocity with the mean of the velocity graph. To find position the software computes it for you, when you pick the quadratic formula At²+ Bt + C to show up on your graph, which gives you the position of the passenger.
Acceleration of the passenger during the crash: .7921 m/s²
Velocity of the passenger during the crash: -1.048m/s
Position of the passenger during the crash: x = 0.4237t² - 4.984t + 16.72
I would owe a mini cooper since, I am a bit short and I like them. However, physically talking I would not owe a mini cooper just based off the video because the car was easily destroyed and the dummy’s head was going everywhere, I would not like to be either the passenger or driver of a mini cooper during a crash.
