Answer:
14.8 kg
Explanation:
We are given that




We have to find the mass of the pulley.
According to question



Moment of inertia of pulley=

Where 



Hence, the mass of the pulley=14.8 kg
Explanation:
ω = 30 rev × (2π rad/rev) / (6 sec)
ω = 10π rad/s
ω ≈ 31.4 rad/s
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
Answer:
Semen is the most important thing in the life cycle of life
"decreasing the distance of the space shuttle from Earth"
F = Gm(1)m(2)/R²
where R is the distance between the 2 objects, as it decreases, the force increases.
