Linear momentum is in a straight line and depends on the objects mass and velocity.
Angular (rotational) momentum depends on the objects mass, velocity, and radius.
Answer:
Explanation:
angular acceleration α = 6.61 / 8.97 = .737 rad / s²
moment of inertia = 1/3 m L²
= 1/3 x 1.13 x .899²
= .3045 kg m²
torque applied = moment of inertia x angular acceleration
= .737 x .3045 = .2244
If be the force
Torque
= F x .899 = .2244
F = .25 N ,
Is there a picture so I can help you
You used lengths to calculate the volume.length is considered one dimensional.while volume is considered 3 dimensional.you used 3 individual dimensions their numerical lengths to find volumes of three dimensional figures.
Answer:
Free-fall is defined as the movement where the only force acting on an object is the gravitational force.
By the second Newton's law, we have that:
F = m*a
Where F = Force, m = mass, a = acceleration.
We can write this as:
a = F/m
And the gravitational force can be written as:
F = (G*M/r^2)*m
Where G is the gravitational constant, M is the mass of the Earth in this case, and r is the distance between both objects (the center of the Earth and the free-falling object)
As the radius of the Earth is really big, the term inside the parentheses is almost constant in the region of interest, then we can write:
G*M/r^2 ≈ g
And the gravitational force is:
F = g*m
And by the second Newton's law we had:
a = F/m = (g*m)/m = g
a = g
Then the acceleration does not depend on the mass of the object.
Then the thing that is common among the free-falling objects is the vertical acceleration.
