Term (symbol) Meaning
Standing wave Waves which appear to be vibrating vertically without traveling horizontally. Created from waves with identical frequency and amplitude interfering with one another while traveling in opposite directions.
Node Positions on a standing wave where the wave stays in a fixed position over time because of destructive interference.
Antinode Positions on a standing wave where the wave vibrates with maximum amplitude.
Fundamental frequency Lowest frequency of a standing wave that has the fewest number of nodes and antinodes.
Harmonic A standing wave that is a positive integer multiple of the fundamental frequency.

either multiply 128 by .5 until you get to 2 counting each time or use 2 formulas ln(n2/n1)=-k(t2-t1) to get k then input k into ln(2)=k*t1/2
n2 is final amount and n1 is beginning and t is either time elapsed as in the first formula or the actual half life that is t1/2
Explanation:
To solve this problem it is only necessary to apply the kinematic equations of angular motion description, for this purpose we know by definition that,
Where,
Angular Displacement
Angular Acceleration
Angular velocity
Initial angular displacement
For this case we have neither angular velocity nor initial angular displacement, then
Re-arrange for 
Replacing our values,
Therefore the ANgular acceleration of the mass is
