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:
Given:
mass of the ball m = 0.144 kg
velocity v = 38 m/s
now, change in momentum
P = m v- ( - mv)
= 2 mv
=2 x (0.144) x (38)
= 10.944 kg-m/s
Impulse J= F. Δt
change in momentum is equal to impulse
J = 10.944 kg-m/s
we know force is equal to change in momentum per unit time
F = 13.68 x 10³ N
F = 13.68 kN
