Use the velocity components to determine the direction of the velocity vector. Is it in the expected direction?  Yes the velocity vector was moving in the expected direction using the velocity components.  2. Analyze enough different points in the same video to make a graph of speed of a point as a function of distance from the axis of rotation. What quantity does the slope of this graph represent? The slope of this graph represents the angular velocity. 3....

Designing and creating the cart used in our presentation using materials scavenged at home.  helped organize the slides by inputting images of our computational graphs along with pictures of the cart and a video of both the cart and computational model running. Also helped with writing our goals and how we designed the cart slide. Put in photos of our labs we did into the presentation that were used to calculate values and towards creating the cart.  Stayed communicative with my group by creating our own discord group!  Provided a video of the cart to help create the computational model of our cart. 

 Analysis Determine the final angular velocity of the ring/disk/shaft/spool system for each case after the weight hits the ground. How is this angular velocity related to the final velocity of the hanging weight?  Be sure to use an analysis technique that makes the most efficient use of your data and your time.  If your calculation incorporates any assumptions, make sure you justify these assumptions based on data that you have analyzed.   Conclusion In each case, how do your measured and predicted values for the final angular velocity of the system compare? They compare pretty well with 2 of them matching and trial 2 or pulley 2 being slightly off from the predicted value.  Of the three places you attached the string, which produced the highest final angular velocity?  Did your measurements agree with your initial prediction?  Why or why not?  What are the limitations on the accuracy of your measurements? Trial 1 which was the largest pulley prod...
