We haven't gone over what offset current compensation is actually. I am also not sure what exactly a voltage divider is. But as to the question, I meant that the R3 and R4 would be 1k, not all of them. Are you supposed to turn Vs2 off to calculate Vs1?

Ok so for the v2 I got -R2/R1(v2) so that would be -3/1 so for v1 I get 1+3/1 * R4/R3+R4 So that means it needs to be 1/2 so all of the Rs must be 1?

I didn't do the long work in that message, but that's what it came out to I brought the 1/2 x 9.81 x 270 squared to the other side and then divded by 450 + 30 x 270

Nm I did a calculation error. I now did 0 = 450a + 30a(270) - 1/2 (9.81)(270)^2 = 70 ms-2

So a = 176 ms^2?

Plugging that back into my first equation I get that V = a(30) and a = 88.3

To find the V for the first equation, I know that it is the initial velocity in the second equation. so for the 2nd equation I got V = Vo + at 0 = Vo + (-9.81)(270) v = 0 because that is when the rocket lands. with this equation I got that Vo = 2648.7

Y = 1/2 at,^²

V/t = a for the first phase t is 30.

OK so my first equation would v/30 = a because V = Vo + at and Vo = 0.

Yes, I thought that g was always in affect when you look at acceleration in the y direction. This is what i worked out, does this make sense: part a v=0 at top point v= vo+(a-g)t vo= (a-g)*30 ...P v^2 = u^2 +(a-g)s vo^2 = (a-g)s ....Q time taken for free fall = 300-30= 270s so v at ground=...

For V1, I get V= Vo + At V = (a-g)t

First the first stage, shouldn't I take into account the -9.81 effect of gravity?
