One of the components that affect the period is gravity (the other is length). This gravity is basically the value of the effective acceleration that acts on the body due to gravity. When the elevator is over free fall, the effective gravity becomes zero. Mathematically this can be visualized as,
Since this value is zero, the period would tend to be infinite,
Therefore the frequency that is inversely proportional to the period would be defined as
In this way there is no frequency on the body which will not generate any oscillation on the body
Answer:
Explanation:
the maximum speed is reached when the drag force and the weight are at equilibrium, therefore:
To calculate the velocity after 100 meters, we can no longer assume equilibrium, therefore:
(1)
consider the next equation of motion:
If assuming initial velocity=0:
(2)
joining (1) and (2):
(3)
To plot velocity as a function of distance, just plot equation (3).
To plot velocity as a function of time, you have to consider the next equation of motion:
as stated before, the initial velocity is 0:
(4)
joining (1) and (4) and reducing you will get:
solving for v:
Plots:
