I have the following problem, Im not sure this is a calculus problem but I didnīt know where else to post it...
A body is found in a room with the temperature 5degrees.
Att 06.00 the body temperature is 23 degrees
att 08.00 the temperature is found to be 18.5degrees.
When did the murder occur?
Suppose to you Newtons cooling law: y' =-k(y-yg) there yg = temperature of the room...
Well so I have y' = -ky +ky(g) = y' +ky = 25k
So the general solution is y = Ce^(kx)
The body temp at the murder was 37degrees
And here Im stuck....
Also I donīt want to getting any more warnings so does anyone know how I report the post? So I can tell the admin I didnīt know where to post it?
