    How to find the equilibrium point between two masses? (Topic 6.2)

    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...

    Solve for the total Kinetic Energy change with unknowns

    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)} =...

    Solve for the total Kinetic Energy change with unknowns

    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?

    Solve for the total Kinetic Energy change with unknowns

    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...

    Solve for the total Kinetic Energy change with unknowns

    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...

    Distance Velocity Graph: What Does the Area Represent?

    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...
