The formula for momentum is p = m*v
The conservation of momentum suggests:
m*vi = m*vf (initial mass times initial velocity = final mass times final velocity or initial momentum = final momentum)
(0.0010)(52.2) = (0.0010 + 3.3)vf
vf = (0.0010)(52.2)/(0.0010 + 3.3) = 0.0522/3.301 ≈ 0.01581 m/s
To the nearest thousandth ≈ .016 m/s
A box with 10 baseballs because the balls have less mass therefore feel more pull from the earth
Answer:
The moment of inertia of the system is
Explanation:
From the question we are told that
The mass of the platform is
The radius of the platform is r = 1.95 m
The mass of the person is
The position of the person from the center is
The mass of the dog is
The position of the dog from the center is
Generally the moment of inertia of the platform with respect to its axis is mathematically represented as
The moment of inertia of the person with respect to the axis is mathematically represented as
The moment of inertia of the dog with respect to the axis is mathematically represented as
So the moment of inertia of the system about the axis is mathematically evaluated as
=>
substituting values
Answer:
It can be either, depending on how much and how you add the electrons
Atoms of the same element having equal numbers of protons, but different numbers of neutrons is called isotope.
