An object has rotational inertia i. the object, initially at rest, begins to rotate with a constant angular acceleration of magnitude α. what is the magnitude of the angular momentum l of the object after time t? express your answer in terms of i, α, and t.

Explanation:

initial angular velocity, ωo = 0

angular acceleration = α

time = t

let the angular velocity after time t is ω.

Use first equation of motion for rotational motion

ω = o + α t

ω = αt

The angular momentum is given by

Angular momentum = moment of inertia x angular velocity

L = I x ω

L = I x αt

L = I α t

The angular momentum of the object in terms of angular velocity, time of motion and angular acceleration is L = Iαt.

The given parameters;

The final angular velocity of the object is determined using first kinematic equation;

The angular momentum of the object is calculated as;

Thus, the angular momentum of the object in terms of angular velocity, time of motion and angular acceleration is L = Iαt.

what is the question because that is not a question.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
