How do I combine equations for absolute independent motion with pulleys?
Homework Statement I've been given a problem with pulleys which I have attached to this post. I've derived the equations shown in the post but I'll also write them below. What I'm struggling with is how to combine them. Homework Equations ##l_1=S_a+2S_c## ##l_2=S_d+(S_d-S_c)##...- JustDerek

How do I find distance given time and an arbitrary distance?
Ah yeah. Good point. I won't try and input anymore I've already been wrong once- JustDerek

How do I find distance given time and an arbitrary distance?
I'm not 100% sure as I'm just learning this stuff myself. But I think you can work out the velocity to the bottom of the window by just doing ##v_1=d/t## calling this velocity ##v_1## then put this in as an initial velocity in your ##v=v_0+at## to find out your v over the two seconds. Then use...- JustDerek

What is the final pressure in the balloons after being disconnected?
I'm not sure as I'm only just learning this stuff myself though it appears I'm a couple of weeks behind you but wouldn't it be worth finding the mass flow rate? Sorry if that's wrong.- JustDerek

Thanks for all your help. I'll see what I can do from here. You've been a saint I'd give you +100 likes if I could- JustDerek

Magnitude of velocity and acceleration
Never done that before but I'll look into it. Won't that give multiple values for t?- JustDerek

Magnitude of velocity and acceleration
Which is get ##524=0.01t^3+5t## which believe it or not I've had worked out for two days. What I don't get is how to isolate t from this- JustDerek

Magnitude of velocity and acceleration
So I make ##a=0 s=524 and V_0=5## and try to solve t for this?- JustDerek

Magnitude of velocity and acceleration
Wouldn't that make c=0 at the start point?- JustDerek

Magnitude of velocity and acceleration
You right I did integrate it wrong it's ##5t## and not ##2.5t^2##- JustDerek

ok now my mind is just gone, I'm going to leave it for a while and come back to it another time- JustDerek

Magnitude of velocity and acceleration
also i know this gives ##524=0.01^3+2.5t^2+c##- JustDerek

Magnitude of velocity and acceleration
I've integrated twice. I got ##v=0.03t^2+5t## and then integrated again to get ##s=0.01^3+2.5t^2+c## but even here I'm unsure how to isolate the t's because they have different powers and values attached to them- JustDerek
