Question

Can someone explain how time was solved?

An object in simple harmonic motion has an amplitude of

4.0 cm, a frequency of 2.0 Hz, and a phase constant of 2pi/3 rad.

Draw a position graph showing two cycles of the motion.

The following table gives the position of the object at different times. x cm 2.0 0.083-4.0 0.3334.0 0.583-4.0 0.8.3334.0 1.083 -4.0

Answer 1

you are not solving here time table. you take any random value of time and for that time you try to calculate the position or what can you do is take a random position and solve for time. Both can be done with the following formula.

x=Acos(wt)

here, A is amplitude, w is angular frequency, t is the time.
