Two projectiles, displacement vs. time

AI Thread Summary
A ball is thrown upward with an initial speed, reaching a maximum height before a second ball is thrown at the same speed. Participants discuss how to sketch a displacement vs. time graph for both projectiles and identify where their paths intersect. The crossing point occurs above h/2 and at 3/4h. One user expresses difficulty with the final calculations, noting the maximum height formula h = vo^2/g. The discussion emphasizes the importance of graphing to visualize the problem effectively.

A ball is thrown upward with an initial speed, vo.
When it reaches the top of its flight, at a height h, a second ball is thrown at the same initial velocity.
sketch a displacement vs time graph for both balls.
where do the balls cross from the graph.
Find the height where the paths cross.

answers: above h/2 and 3/4h

please help

Well ... draw a graph. You have to show us some work before we know what you are having trouble with.
 
And the title could be more descriptive, too.

This is what I have got...
I am having trouble in the last part..
Though I have got h (max ht) = vo^2/g

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...
