The equivalent of the Newton's second law for rotational motions is:
where
is the net torque acting on the object
is its moment of inertia
is the angular acceleration of the object.
Re-arranging the formula, we get
and since we know the net torque acting on the (vase+potter's wheel) system,
, and its angular acceleration, 
, we can calculate the moment of inertia of the system:
where
Re-arranging the formula, we get
and since we know the net torque acting on the (vase+potter's wheel) system,
Answer:
Increase in the temperature of water would be 0.9 degree C
Explanation:
As we know by energy conservation
Change in the gravitational potential energy of the cylinder = increase in the thermal energy of the water
Here we know that the gravitational potential energy of the cylinder is given as
here we have
h = 300 m
now we can say
now if the cylinder falls from height h = 100 m
then we have
now from above two equations
