Hi, Thank you very much for the help, I'm used to solving it with numbers not in problems. It makes all sense now. Once again thank you

Hello, Could anyone please explain me the steps in these pictures. I do not understand the second step. http://imgur.com/AvVbPu5,Ust2Zpx#0 Second one: Third step ( i don't understand) http://imgur.com/AvVbPu5,Ust2Zpx#1 If anyone can give me detail explanation, i would really appreciate it.

That answer doesn't explain anything about the circuit, So I did it wrong, can you please check my work

Homework Statement I'm stuck on finding the inverse of this circuit. Can anyone please check my work, In this circuit you are suppose to find v(t) when switch moves to point 2 ( meaning deattached from battery). Homework Equations The Attempt at a Solution...

Gotcha, Thanks mate. This solves the mystery :) and yes i meant (s+2)^2

Homework Statement Could anyone please check my work, The answer is wrong. Correct Answer: e^2t(-t+e^t-1) Homework Equations Inverse Laplace The Attempt at a Solution Here's my solution, please point out my mistakes. One mistake i found after taking the picture is: Its -2te^-2t ( third...

Can you please show me how to solve it? I want to know how can the solve if its at 14cm above table top

That it's starting to slow down, once it reaches -A it will have 0 velocity and then it will start gaining velocity again. correct ?

Another question will the velocity be same if it was at 14cm above?

I was making this question wayy too complicated for myself, turned out its a super easy question haha

Oh wow i got it haha, Its V=Aω ---> 1.57(.07) --> .11 m/s Now comes the acceleration part ---> a=ω(square) times x ---> 1.57(square) times (0) = 0 Great ! Am i correct?

Haha thanks :) I think because it's at equilibruim state which is its original position. So It should have no velocity or maybe i got the whole concept wrong. Reason I'm asking here is because my next class is on tuesday i don't want to wait that long :)

Homework Statement A 300g mass at the end of a spring oscillates such that it is a 2.0cm above the top of a table at its lowest point and 16cm above at its highest point. Its period is 4s. Find the Speed & acceleration of the mass when 9 cm above the tabletop?Homework Equations F=Kx A...
