Question

For the simple harmonic motion equation d=2sin(pi/3 t) , what is the period?

Answer 1

compare with this equation

y = A sin(wt), where y is displacement, A is amplitude, and w is angular frequency,

now w = 2pi/T where T is time period,

and guess you can find after that

Answer 2

T = 1/6 s

Answer 3

so 6
