Let t be the number of seconds elapsed after the wheel begins rotating counterclockwise. You find it takes 3 seconds to reach the top, which is 53 feet above the ground. The wheel is rotating 12 RPM and the diameter of the wheel is 50 feet. Let d(t) be your height above the ground at time t.
a. Argue that d(t) is a sinusoidal function, describing the amplitude, phase shift, period and mean.
Amplitude: _______
phase shift: ______
period: _______
mean: _______

Answer:

2593 feet

Step-by-step explanation:

The amplitude, phase shift, period, and mean, and the further discussion  can be defined as follows:

  • Amplitude=25
  • Phase shift=1.75
  • Period=5
  • Mean= 28
  • (1.75, 4.25) the first and second time, you are approximately 28 feet off the ground.
  • You will have been exactly 28 feet just above earth 11 times after 29 seconds.
