AI Thread Summary
The discussion centers on calculating average speed and average velocity for a road trip, with particular focus on parts (c) and (d) of the homework. The main equation used is speed equals distance divided by time. There is confusion regarding the correctness of solutions for parts (a) and (b), particularly in understanding the relationship between average velocities and individual velocities. A key point raised is the distinction between speed and velocity, which is crucial for solving the problem. Clarifying these concepts is essential for accurately answering the remaining parts of the assignment.

I haven't worked the problem myself, but I am not sure your solutions to parts a and b are correct. Does it make sense to have average velocities higher or lower than both velocities? Perhaps this is why you're struggling on c and d.

In both a) and b) you got confused between the half (time or distance) and the whole.
For d), what is the difference between speed and velocity?
For d), what is the difference between speed and velocity?
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question.
Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point?
Lets call the point which connects the string and rod as P.
Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is
The second part of the problem is exactly why you get this affect.
And one more spoiler:
F1=(5000+200)g=5200*10=52000N --> F2=(5000+100)g=5100*10=51000N ?
