AI Thread Summary
To determine the velocity required for a 1000 kg car to move uphill on a 0.02 percent grade with a friction value of 0.7, the force can be calculated using the equation F = μmg cosθ, resulting in a force of 6866.99 N. However, the discussion highlights a misunderstanding that forces can be directly converted to velocity, which is not possible. The focus remains on the relationship between force, mass, and acceleration rather than velocity. Ultimately, the thread concludes that the original question may not be well-structured for the physics involved. Understanding the distinction between force and velocity is crucial in solving such problems.

Homework Statement



I'm trying to figure out how much velocity is required to move 1000 kg car up a hill that has a .02 percent grade and a friction value 0.7.


Homework Equations



F= μmg cosθ

The Attempt at a Solution



F = 6866.99 N

If this is correct how do you get this into velocity.

Ah, never mind this question really makes no sense anyway. Obviously we are dealing with forces which can not be changed to velocity. ( ya... I loose arguments with myself all the time).

Thanks

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...

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...
