Homework Statement
http://online.physics.uiuc.edu/cgi/courses/shell/common/showme.pl?courses/phys211/oldexams/exam2/sp08/fig11.gif
A mass m is attached to a spring with spring constant k, the other end of which is attached to the ceiling. It is pulled and allowed to oscillate up and down. Using dimensional analysis, determine which of the following is a valid expression for the time t it takes to complete each oscillation.
(a) t = 2πkm
(b) t = 2π sqrt(m-k)
(c) t = 2π sqrt(m/k)
(d) t = 2π sqrt(k3/m)
(e) t = 2π + m/k2
Homework Equations
The Attempt at a Solution
I tried to solve this problem using 'energy conservation' theorem..
But from there, i couldn't find the factor of the 'time' and when seeing the options given,
I don't even know why "2*pi" is coming into the picture when dealing with spring...
Please could someone help me out here?
