A mass oscillating up and down while attached to the bottom of a spring can be modeled using simple harmonic motion. If the weight is displaced from its equilibrium position a maximum of 7 centimeters and it takes 3 seconds to complete one cycle, answer the following questions:
Amplitude: Is it 7
Period: I got 3, but I think that is incorrect
Frequency: IDK???

mani_jha · Answer

Your answers are right.
Frequency is just the reciprocal of time period..

anonymous · Answer

amplitude :7 is obviously right.
time period:3 because it will be equal to time which is taken by particle to complete one cycle.
frequency is the no of oscillation in one second i.e 1/Time period=1/3=0.33 Hz
