What Is the Spider's Average Speed and Magnitude of Average Velocity?

AI Thread Summary
The discussion revolves around calculating the average speed and magnitude of average velocity of a spider crawling from corner A to corner B. The spider covers a total distance of 48 meters (27 meters from A to C and 21 meters from C to B) in 30 minutes. Average speed is determined by dividing the total distance by the time taken, while average velocity is calculated using the displacement (the straight-line distance from A to B) divided by the same time. The conversation also includes a brief off-topic exchange about the University of North Dakota. Overall, the focus remains on solving the spider's movement problem.

I am having a problem with the following question:
A spider crawls from corner A to corner B in 30 minutes. The distance between AC (C chosen as a half-way point) is 27 meters, the spider turns right and the distance between CB is 21 meters. a) What is its average speed? and b) what is the magnitude of its average velocity?
Thanks for any help!

hey Bianna, is UND Notre Dame or North Dakota (my alma) or something completely different?

I go to University of North Dakota
 
For average speed, divide the distance traveled by the time; for average velocity, divide the displacement by the time.

Thread 'Collision of a bullet on a rod-string system: query'

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...

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
