AI Thread Summary
A skier sliding down a 15-degree slope experiences several forces, including kinetic friction, weight, and the normal force. The discussion clarifies that static friction is not applicable since it relates to initiating movement, while tension is irrelevant in this context. Thrust could be considered if the skier uses poles for propulsion, but it's not essential to the basic analysis. The consensus is that the primary forces acting on the skier are kinetic friction, weight, and the normal force. Understanding these forces is crucial for solving problems related to skiing dynamics.

Quick question about forces!

Homework Statement



A skier is sliding down a 15 degree slope. Friction is not negligible. Identify all forces on the skier.

Homework Equations



n/a

The Attempt at a Solution



The choices are: Tension, Kinetic Friction, Weight, Static Friction, Thrust, and Normal Force.

I drew a picture and assumed Kin. Friction, Weight, Thrust, and normal force were the answers but I got it wrong.

I don't think static friction is the answer because that is used to determine the force that must be overcome to initiate movement. Tension seems like a cable or string thing and not something that would affect a skier. I guess I don't know what thrust is but would it be correct to say that K. Friction, weight, and N. Force are the only forces on the skier or am I missing something? Thank you for your help!

Looks right.

There might be thrust if they were pushing with their arms with their poles, but that sounds beyond the scope of the question.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
Thread 'Voltmeter readings for this circuit with switches'
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...
Thread 'Trying to understand the logic behind adding vectors with an angle between them'
My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
