Speed does not affect the momentum of inertia so that when mass starting downwards with constant speed, this constant speed doesn't affect the measured Momentum of inertia.
Example -
For a ring, I = MR2 ---- (1) where, I = momentum of inertia
M = mass of ring
R = radius of ring
In equation - 1 we see that momentum of inertia affect by the mass and the redius, not affected by the speed.
So momentum of inertia remain unchanged.

INVESTIGATION 10 ROTATIONAL MOTION OBJECTIVE To determine the moment of inertia I of a heavy composite disk by plotting measured values of torque versus angular acceleration. THEORY Newton's second law states that for translational motion (motion in a straight line) an unbalanced force on an object results in an acceleration which is proportional to the mass of the object. This means that the heavier...

4. The starting material, NiCI) 6H O is lime green and the product, Ni(NH>Cl is dark purple. Suppose that over the course of one week, the storage vial was not capped properly and the dark purple product absorbed some water from the air, lost some NHi gas and reformed some of the starting material. This is often evident as a light green "crust" around the dark purple product after storage. How would reformation of the starting...

1a.) Let us first ask what we mean by "uniform acceleration." After all, a rocket approaching the speed of light c can't change its velocity at a uniform rate forever without exceeding c at some point. Go into the frame moving instantaneously at velocity v with the rocket relative to the "lab." The instantancous rocket velocity, v, vanishes in this frame. Wait a time dt later, as measured in this frame. The rocket now has velocity do' in this same...

Suppose an oil company is considering whether to develop production facilities for a newly discovered oil field on lands owned by a state government. If the firm spends $2 billion in present value in capital costs, it could install facilities capable of producing 80,000 barrels per day. Annual operating costs for the oil field are anticipated to be $30 per barrel produced. The company expects production from the field to start at 80,000 barrels per day but then decline at...
