What is the magnitude of the speed of a person at the equator due to rotational speed of the Earth?

Physics

The circumference of the Earth at the equator is listed as 24,901 miles.
So his speed is

                     24,901 miles per day.

Convert it to units that we have a better feel for:

                   (24,901 mi/da) x (1 da / 24 hrs)

             =    (24,901 / 24)  (miles/hour)

             =  about  1,038 miles per hour.

You'll find a huge number of people on the internet these days,
telling you that you could not be moving at that speed and not
feel it, so therefore the Earth is not spinning, and it's not a globe.

I have a lot of feelings and comments about those people, their
lines of reasoning, and their levels of education and intelligence,
so don't get me started.

I just want to guarantee you that everything you're learning about
the Earth and the solar system in school is well founded, and it's
all based on the life's work of some of the smartest people of the
past 300 years of human history.  Everything you're taught about
the Earth has good reasons behind it, whereas those other people
have nothing.

A person on Earth's equator is moving from west to east at roughly
1,038 miles per hour, relative to any point on the Earth's rotation axis.

A Jeep Rubicon has a mass of 2,630 kg. With a momentum of 55,200 kg m/s. What was the speed, in m/s, of the vehicle?
Annette [7]

Answer:

The speed of the vehicle was 21 m/s

Explanation:

Momentum can be defined as mass in motion

Momentum depends on the variables mass and velocity

The momentum of an object is equal to the mass of the object times the

velocity of the object

The given is:

→ A Jeep Rubicon has a mass of 2,630 kg

→ With a momentum of 55,200 kg m/s

We need to find the speed of the vehicle

→ The momentum = mass × speed

Substitute the values above in the rule

→ 55,200 = 2,630 × speed

Divide both sides by 2,630

→ speed = 20.99 ≅ 21 m/s

<em>The speed of the vehicle was 21 m/s</em>

The low-_____ areas in a sound wave are called rarefactions. A. period B. frequency C. energy D. density
Delicious77 [7]
You can picture a sound wave a lot like a Slinky wave . . . a
thicker, compressed blob moving along the path, with thinner,
stretched-out places before and after it.

The thicker parts of a sound wave, where the air is more dense,
are called compressions.

The thinner parts of a sound wave, where the air is less dense,
are called rarefactions.

Two different blocks of ice sit on the level floor of a meat packing plant. Yasmeen pushes with a horizontal force of magnitude
vlada-n [284]

Answer:

The mass is m_1 =  3m

Explanation:

Generally from Newton law for the first block

F = ma

=>    a =  \frac{F}{m}  

For the second block the force is  F_1 =  2F  and the acceleration is  a_1 = \frac{2a}{3}

So  from Newton law

      2F = m_1*\frac{2a}{3}  

=>   3F  =  m_1 * a

substituting for a

=>    3F  =  m_1 * \frac{F}{m}

=>    m_1 =  3m
