Homework Statement
Hi,
I'm stuck on some question..
There are given to waves in the following equation:
The question asks to find the energy density of them, and after it to find the kinetic and the potential energy in t = 2.5 seconds.
V = | 2 | [m/s]
T = 4 [N]
p (density) = 1 [KG/M]
Homework Equations
The Attempt at a Solution
[/B]
to find the energy density I used this equation:
the solution to this equation (that equals to energy density) is:
then, I've set in place t = 2.5, and the energy density is equal to:
which is great. but my problem is to find the kinetic and the potential energy in t = 2.5 seconds.
I've not understood this question well.
I can find the TOTAL energy by using integral of the energy density to 'dx'.
How can I find the specific kinetic or potential energy?
Thanks.
