Hey guys, I am rather stuck with my work from College, I missed a bit of College as I was having treatment for Cancer, and so I missed a lot of work :frown:, but I'm desperately trying to catch up! If anyone could help me with my work, I would really appreciate it, thank you guys/gals!

For question 1, I got the answer: .04T

0.4 = V Final Velocity

V=U+AT

10 / T
_____
T mps which is my accelerationt= v-u
--------
a

t= 0.4 - 0
----------
10
----------
T

Time = .4
----
10 T = 0.4T

Am I right or wrong? any help please guys!

Thread 'Modeling a graph that shows age in relation to depth of an ice sample'

To solve this, I first used the units to work out that a= m* a/m, i.e. t=z/λ. This would allow you to determine the time duration within an interval section by section and then add this to the previous ones to obtain the age of the respective layer. However, this would require a constant thickness per year for each interval. However, since this is most likely not the case, my next consideration was that the age must be the integral of a 1/λ(z) function, which I cannot model.
