Question about Velocity, time, height

AI Thread Summary
To solve the problem of an object thrown upwards reaching a maximum height of 100 m, the relevant equations of motion, specifically the SUVAT equations, should be utilized. The initial velocity (V0) can be calculated using the equation for maximum height, which relates initial velocity and gravitational acceleration. The total flight time can be determined by analyzing the time taken to reach the maximum height and doubling it. Additionally, the height of the object at a velocity of 30 m/s can be found using the appropriate SUVAT equation. Understanding and applying these equations will lead to the correct solutions for the homework questions.

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...
