The top box is cell and I’ll look at the others
Distance/time=speed
1500/18=83
=83 m/s
Answer:
3. none of these
Explanation:
The rotational kinetic energy of an object is given by:
where
I is the moment of inertia
is the angular speed
In this problem, we have two objects rotating, so the total rotational kinetic energy will be the sum of the rotational energies of each object.
For disk 1:
For disk 2:
so the total energy is
So, none of the options is correct.
The <span>x-values equal time (usually in seconds according to physics position vs. time graphs) and the y-values equal distance (usually in meters according to physics position vs. time graphs). I hope the answer helps. Thank you for posting your question here. </span>
