-/1 points When determining the equation for the moment of inertia of, for example, a thin rod, we will have to perform a(n) o miraculous feat of ingenuity o difference of quotients o integral o derivative o sum /1 points 2 2 The moment of inertia of a solid, uniform sphere of radius R and mass M about an axis through its center is equal to_ 2 MR o 3MR2/5 2MR 2 /1 points The work done in speeding up a rotating tire is simply equal to the o work done by gravity o change in momentum of the tire work done by the road on the tire o net impulse on the tire o change in rotational kinetic energy of the tire -11 points In finding the moment of inertia of a diatomic molecule, the authors used the fact that o each atom acts like a sphere o the two atoms are effectively point masses, so a summation could be used instead of an integral the rotational inertia is just the mass of the atoms "r-perpendicular" is just the radius of each atom o the two atoms are constantly vibrating, so the total kinetic energy must also include vibrational kinetic energy

Explanation / Answer

1) Integral

Deriving moment of inertia involves integration of length and mass.

2) Moment of inertia of a solid uniform sphere is:

2MR2/5

3) Rotational kinetic energy of the tire.

This is according to the work energy theorem.

4) not sure.
