Morning all I've recently come across a problem where I get conceptually but cannot apply mathematically if that makes sense. I understand the position of the third mass must be at the equilibrium point of ##m_1## (##9.0×10^{24}kg##), so ##\Sigma F = 0## right? And not even necessarily zero...

Yep. That's what I did and I ended up with an actual answer to my surprise. It's fascinating how you can have so little information and still deduct something from a system. First, I realized that the end result is a compound of the two ##E_k##, so I wrote out. ## \frac 1 2 {(2m)}{(v^2)} =...

I am new to maths entirely (as in I spent June-July learning all of Algebra), so would I do ##E_k1 = E_k2##? Or just stick to what I did up in my original post?

Ah, I see. You god damn geniuses. The reason I ask this is that I've come across questions like this before that seem unsolvable. But are really not, they sometimes give you actual answers. So I'm just wary about picking random values. I have to go learn conservation of energy and the like. I...

Firstly I tried defining into an equation to make the whole thing more 'tangible'. ##m_1= Paula's~Weight⋅2 = m_p⋅2## ##m_2= \frac {Dave's~weight}{2} = \frac {m_d}{2}## Before impact ##E_k1= \frac 1 2 (m_p⋅2)(0^2)## ##E_k1= \frac 1 2 (2m_p)## ##E_k1= m_p ## After Impact ##E_k2= \frac 1 2...

Summary: Gradient = Acceleration(?) Area = Time (?) Good evening, I have a problem that presents itself in a distance (y) velocity (x) graph. I've never come across this, and in my Physics textbook, the section dedicated to graphs does not have it. My question is, what does the area of the...
