Answer:
The moment of inertia of the system decreases and the angular speed increases.
Explanation:
This very concept might not seem to be interesting at first, but in combination with the law of the conservation of angular momentum, it can be used to describe many fascinating physical phenomena and predict motion in a wide range of situations.
In other words, the moment of inertia for an object describes its resistance to angular acceleration, accounting for the distribution of mass around its axis of rotation.
Therefore, in the course of this action, it is said that the moment of inertia of the system decreases and the angular speed increases.

Answer:
![v=697.2km/h](https://tex.z-dn.net/?f=v%3D697.2km%2Fh)
Explanation:
Hello.
In this case, since the velocity is computed via the division of the distance traveled by the elapsed time:
![V=\frac{d}{t}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7Bd%7D%7Bt%7D)
The distance is clearly 1743 km and the time is:
![t=2h+30min*\frac{1h}{60min} =2.5h](https://tex.z-dn.net/?f=t%3D2h%2B30min%2A%5Cfrac%7B1h%7D%7B60min%7D%20%3D2.5h)
Thus, the velocity turns out:
![v=\frac{1743km}{2.5h}\\ \\v=697.2km/h](https://tex.z-dn.net/?f=v%3D%5Cfrac%7B1743km%7D%7B2.5h%7D%5C%5C%20%5C%5Cv%3D697.2km%2Fh)
Which is a typical velocity for a plane to allow it be stable when flying.
Best regards.
The maximum speed of the donkey is 10.72m/s
The question is based on the principle of motion in one dimension and hence formulas of motion in one dimension can be applied.
It is given that donkey attains an acceleration of 1.6 m/s^2
The time taken to accelerate to given speed is 6.7 seconds
We use the formula v=u + at to find the fastest speed
v is the final or maximum speed
u is the initial speed which in this case is 0 as the donkey is at rest
a is the acceleration of the donkey
t is the time taken in seconds
v = u + at
v= 0 + 1.6 x 6.7
= 10.72 m/s
Hence the donkey obtains the speed of 10.72 m/s
