AI Thread Summary
To calculate the distance a car coasts before stopping, given an initial speed of 45 km/h and a constant deceleration of 0.50 m/s², the correct approach involves using kinematic equations. The time taken to stop can be calculated as 90 seconds, leading to a stopping distance of 1125 meters. Additionally, the distance traveled during the first and fifth seconds can also be determined using the same kinematic principles. The initial calculations presented were incorrect, indicating a need for a clearer understanding of the equations involved. Accurate calculations are essential for solving this type of physics problem effectively.

i came up with 11.25min to stop and it'll travel 1125 m before it stops?
 


Can you show you calculated those numbers?
 
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 '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...
