To solve this problem it is necessary to apply the concepts related to the Period of a body and the relationship between angular velocity and linear velocity.
The angular velocity as a function of the period is described as
Where,
Angular velocity
T = Period
At the same time the relationship between Angular velocity and linear velocity is described by the equation.
Where,
r = Radius
Our values are given as,
We also know that the radius of the earth (r) is approximately
Usando la ecuación de la velocidad angular entonces tenemos que
Then the linear velocity would be,
x
The speed would Earth's inhabitants who live at the equator go flying off Earth's surface is 463.96
The formula for working out kinetic energy is
=122
KE = kinetic energy
m = mass of a body
v = velocity of a body
kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.
For the first one I think :
Answer:
KE = 330750 J
I’m not sure about the second one- sorry
The third is
Answer:
KE = 41454 J
Hope it helps and it is correct, sorry if it isn’t !
Answer:
20 watts
Explanation:
Big brain mode activated:
Power=1200J/60sec
Power=20 watts
Answer:
Explanation:
We know that , If the frictional force on a system is zero , then the total energy of a system will be conserved.
By using energy conservation
KE₁ + U₁ = KE₂ + U₂
KE₁=Kinetic energy at location 1
U₁ =Potential energy at location 1
KE₂=Kinetic energy at location 2
U₂=Potential energy at location 2
Therefore, Raymond is thinking in a right way.
