I know this is not a fair way to solve like this.But i didnt have much time to try.If some one help me whit the solutions i will be really happy.

This is the my homework.Who can solve this for me ? i upload my solutions and the problem .Thanks.

Hi again.My teacher told me everythink is true except elasticity coefficient ce of reduced spring - and Vo for t=0, if the law of motion x(t) is given x(t)=0,4 cos 4t+0,5 sin 4t ...Thanks again.

@ehild I am very happy to meet whit you.Thank you very much.You helped me and tried to teach my classmates.We will get higher marks i am sure .Thanks again .

Yes i know a little.First derivative of displacement is velocity.And second derivative of displacement is acceleration. So İf t=0 then x0=0,4 ...And first derivative of x(t)=0,4cos4t+0,5sin4 is 0 isn't it ? Then Vo is equal 0 ? ( Derivative of constant number is 0 ) ? :S

I think i found some answers.in the attachments...Please can you check ? this are 3-4-5 part of my question.What about the first and second part. For second part. (For t=0 values for initial conditions x0 and v0 ) x(0) = 0,4 cos (4x0)+0,5 sin (4x0) ===> Cos 0 = 1 and Sin 0 = 0...

Can you help whit numbers because my english very bad.Its not my main language :( x(t) =asin(ωt)+bsin(ωt) this is formul. And x(t)=0,4cos4t+0,5sin4t how can i compare . And note i am in high school.I thınk this kind of questions are hard for us ...I don't know where can i start.Please...

I got some ideas for the 3rd part of question. I have to find natural frequency. And for this need The natural period of the oscillation . And the natural period of the oscillation formulas in the attachment 2. (down) And the naturel frequency formula is it the attachment 1. (up) This are true...

[FONT="Comic Sans MS"][SIZE="3"]Problem A vertical oscillating system consist of three equal springs with elasticity coefficient c , among which a mass m=2kg is suspended.The system oscillates according to the following law of motion x(t)=0,4 cos 4t+0,5 sin 4t , (m) . Determine: 1) The...

up up up ...I need this question for 2 days later...Cmon people Help.I know a lot of well-informed man in this forum...

Homework Statement Homework Equations The Attempt at a Solution Hi from Turkey...I really need to solve this 3 problem...I will enter exam whit same problems...I have some attempt but i really need to exatly result...Because our teacher doesn't give mark your solving way...So...

Thanks for the hint :)...Here is the my answer can you please check it ..First picture is for the point P..I draw The all necessary points and shafts. Second picture is for the solving way...I am really glad to meet you :) ( sory for my language its not my main )

aha i am sory about this...Here you are...yes alpha and Beta i think are equal...and then Vc is equal too ...Now i need one more help for angulae velocities ...thanks again :)

Thanks for Help ..Here is the my answers..But how can i find Vc...and angular velocities..

Va = 0,6m/s ...but i am not sure others..Please help me for others..Because Va is easy..But others are hard for me because i am high school :(
