Posted:Solve this:

A mass of 5 kilograms compresses a spring 9.8 centimeters from its
equilibrium position. The mass is attatched to a damper with coefficient F,
and set it motion from 5 centimeters above equilibrium with a downward
velocity of 10 meters a second. The system is acted upon by an external
force of 12cos(3t)+3sin(3t).
A) Find the position of the block at any time.
B) Determine the value of F where the system is critically damped.
C) Determine time T when the block passes through the equilibrium position
the 4th time going downward.

Basically you have something on a spring and you press down on it. You have to find an equation that satisfys its position at any given time.

ubbrollsmile dont ask why.... im bored biggrin

Posted:eek should i be able to remember this from A-level physics?? no, the real question there is can i remember anything from A-level physics, and the answer to that is a categorical, no. So I'll just.... I'll just go now.... *wrinkles nose and heads to door*

btw, if you're bored, shouldn't we be setting the questions and you can work on the answers?? biggrin

Anyone else know complex things with which we can quiz tutuman??

No TuTuMan, you can keep doing random posts. Just be aware that there is always the possibility that it will be hijacked to another destination. tongue

Or at least you could give us a multiple choice... In which case I choose B. My chances of getting the correct answer are the same weather or not I know the options.
