    Force Slope
AI Thread Summary
To solve for Franz's acceleration while skiing down a 50-degree slope, the mass can be represented as 'm', allowing for the calculation of acceleration in terms of 'm'. The kinetic friction coefficient is 0.05, which plays a crucial role in determining the net force acting on the skier. The forces acting along the slope include gravitational force and friction, which can be expressed mathematically. Ultimately, the mass 'm' cancels out in the calculations, simplifying the process. Understanding these concepts allows for the accurate determination of acceleration without needing the specific mass value.

[SOLVED] Force on a slope

"Franz is skiing in the Alps. He is racing down a steep slope of 50.0 degrees. For waxed skis on snow, we have mu sub k (for kinetic friction)=0.05. What is his acceleration?"

I'm so confused... don't I need his mass to even begin to approach this or am I missing something?
 
Physics news on Phys.org
let m be the mass... get the acceleration in terms of m... (the m's will cancel out when you work out the acceleration).

What is the force acting on the skier along the slope in terms of m...
 
Oh, right. Got it, thank you!

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 '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...
