A Ferris wheel 50ft in diameter makes one revolution every 40sec. If the center of the wheel is 30ft above the ground, how long
aleksklad [387]

Answer:

The rider is 15.91  seconds  50 ft above the ground after reaching the low point

Step-by-step explanation:

We can evaluate the angle  α

using trigonometry applied to the orange small triangle with height 50-30 = 20 ft and  hypotenuse equal to the radius  r = 25ft

Now

20 = \frac{25}{sin(\alpha)}

\alpha = arcsin{\frac{20}{25}

\alpha = 53.13^{\circ}

So  50 ft  of height corresponds to the total angle:

90^{\circ} =53.13^{\circ} = 143.13 6^{\circ}  = 2.498 radians

Now the angular velocity

\omega = \frac{2\pi}{T}

\omega = \frac{2 \pi}{40}

\omega =0.157rad/s

To describe  2.498  rad  it will take:

t = \frac{2.498}{0.157}

t = 15.91 s

Oduvanchick [21]
The beginning has 12 seconds, the middle part has 36 and the end has 72 seconds.

Let’s separate the song into three parts and write and equation that equals to 120 seconds.

120= x + 3x + 6x

120= 10x

X=12 seconds
