Did you know that the motion of a mass suspended from a spring can be modeled by sinusoidal equations?
In the given scenario, a mass is pulled down 30 cm from its rest position and released to oscillate. If the mass returns to its initial position after 2 seconds, we can find two different sinusoidal equations to describe this motion. These equations will help us understand the position of the mass at any given time.
One possible sinusoidal equation is:
y(t) = A sin(2π/T * t)
In this equation, A represents the amplitude of the oscillation, which can be determined by the initial displacement of the mass (30 cm). T represents the period of the oscillation and can be calculated by dividing the time taken to return to the initial position (2 seconds) by the number of oscillations (1 since it returns to the initial position only once). Thus, T = 2 seconds.
Another possible sinusoidal equation is:
y(t) = A cos(2π/T * t)
This equation is similar to the previous one, but uses a cosine function instead of sine. The choice between using sine or cosine depends on the initial conditions and the position of the mass at t = 0.
By utilizing these sinusoidal equations, we can better comprehend and predict the behavior of the mass as it oscillates back and forth.
