2. Relevant equations

3. The attempt at a solution

Problem #1)

I do not know where to proceed from here

I have.

T = 2pi * square root of L/g

where T = time, g = acceleration

L = length

I know that acceleration = Length/Time^2

so I get

T = 2pi * square root of L/(L/T^2)

I also do not understand how 2pi eventually plays a part in this.

Problem #2)

I honestly do not know where to start with this problem. If I understood the first part, the second part wouldn't be a problem. What does kg.m^2/s^2 mean?

I know that these are very basic questions, but my book assumes a lot and takes leaps and I unfortunately need things spelled out for me from time to time. Any help given is more than appreciated. :)
