AI Thread Summary
In a tug of war on a sandy beach, Team A has six players averaging 65 kg, while Team B has five players averaging 84 kg. Team B exerts a pulling force of 3200 N to dislodge Team A and then maintains a force of 2900 N to keep Team A moving at constant velocity. The static friction coefficient for Team A is calculated as 0.22 based on the normal force and the applied force. The discussion highlights the importance of considering all players' weights in calculating friction dynamics. Understanding these forces is crucial for analyzing the physics of tug of war.

Homework Statement



In a game of tug of warcontest on a firm, horizontal sandy beach, Team A consists of six players with an average mass of 65 kg and Team B consists of 5 players with an average mass of 84 kg. Team B pulling with a force of 3200 , dislodges Team A and then applies good physics principles and pulls on Team A with a force of 2900 , just enough to keep Team A mov ing a at constant velocity. What is Team A's?
a. static friction
b. kinetic friction

Homework Equations


uS = Fs/Fn
uK = Fk/Fn


The Attempt at a Solution


Fn = Fg = mg
65 kg x 9.8N/kg
637 N
uS = 637 N/2900N
0.22

You haven't stated a question. What's the purpose of your post?

It might be of interest to note that you've disregarded five of the six players on team A.

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
