Calculating Friction Force: 800N Weight & 15° Angle

AI Thread Summary
To calculate the maximum friction force generated while running with an 800 N weight and a backward force of 1000 N at a 15° angle, the coefficient of friction is 0.09. The discussion emphasizes the need to resolve the forces into their horizontal and vertical components using trigonometric functions. The horizontal component of the force is calculated as F=urSin15, while the vertical component is F=urCos15. Participants suggest drawing a diagram to visualize the forces acting on the runner for better understanding. The conversation focuses on applying these principles to determine the actual friction force experienced.

Here's there problem:
You are running, your weight is 800 N. You generate a backward and downward force of 1000 N at an angle of 15 degrees from vertical. What is the maximum friction force you can generate and the actual fritction force generated between the surface area and your shoe. Coefficient of friction=0.09

im not sure how to start this i have been using the F=ur but I am not sure how the angle works into everything. Thank You sooooooo much :cry:

But can you draw the figure and list all the forces applied to You ?
I think I can help you, but first you should draw and post the picture...
 
I think, for Ox, you have F=urSin15
for Oy you have F=urCos15
 

Thread 'Rolling without slipping on a curved surface'

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...
