Answer:
<h3>30m</h3>
Explanation:
Velocity is the change of rate of displacement with respect to time.
velocity = displacement/time
Given
initial velocity = 15 m/s.
time taken =2 secs
Required
Displacement of the object
From the formula;
Displacement = Velocity * time
Displacement = 15 * 2
Displacement = 30m
<em>Hence the displacement of the object is 30m</em>
This statement is
false.
The correct statement would be,
"W<span>hen you approach an
intersection and see a truck ahead signaling a right turn, you should stay
behind the truck,
away from the curbside, until the turn is completed."
Larger vehicles require a larger space to turn, being next to the truck and close to the curbside will only make it more difficult for the truck driver to complete the turn. This in turn will waste more time or even block traffic while the truck driver tries to complete the turn in the difficult situation that could have easily been avoided.</span>

Answer:
I = 0.0025 kg.m²
Explanation:
Given that
m= 2 kg
Diameter ,d= 0.1 m
Radius ,![R=\dfrac{d}{2}](https://tex.z-dn.net/?f=R%3D%5Cdfrac%7Bd%7D%7B2%7D)
![R=\dfrac{0.1}{2}](https://tex.z-dn.net/?f=R%3D%5Cdfrac%7B0.1%7D%7B2%7D)
R=0.05 m
The moment of inertia of the cylinder about it's axis same as the disc and it is given as
![I=\dfrac{mR^2}{2}](https://tex.z-dn.net/?f=I%3D%5Cdfrac%7BmR%5E2%7D%7B2%7D)
Now by putting the all values
![I=\dfrac{2\times 0.05^2}{2}](https://tex.z-dn.net/?f=I%3D%5Cdfrac%7B2%5Ctimes%200.05%5E2%7D%7B2%7D)
I = 0.0025 kg.m²
Therefore we can say that the moment of inertia of the cylinder will be 0.0025 kg.m².
