Answer:
Potential energy: stored energy
Explanation:
Energy is the capacity to do work. It exists in various forms which can be converted from one form to another. It is measured in Joules (J).
The energy possessed by an object at rest is called potential energy. It is a form of mechanical energy. It is a stored energy which can be converted to kinetic energy when the object start to move.
The best match between an established energy type and its use or trait as given in the question is: Potential energy: stored energy

Answer:
T = mg - (m²g/(I/R² + m))
Explanation:
Let T be the tension in the cable between the drum and the bucket
Now, by applying newton's second law of gravity on the downward movement of the bucket, we will obtain;
mg - T = ma - - - - (eq1)
Now, on the drum , a torque of TR will be acting which will create an angular acceleration of "α" in it.
Where R is the radius.
Let "I" denote the moment of inertia of the drum. Thus, we have;
TR = Iα
Now, the angular acceleration is expressed in the form;
α = a/R
Where a is the linear downward acceleration.
Thus;
TR = Ia/ R
T = Ia/ R²
Let's put Ia/ R² for T into equation 1 to give;
mg - Ia/R² = ma
Ia/R² + ma = mg
a( I/R² + m) = mg
a = mg/(I/R² +m)
Now putting mg/(I/R² +m) for a in eq 1 gives;
mg - T = m(mg/(I/R² +m))
T = mg - m(mg/(I/R² +m))
T = mg - m²g/(I/R² + m)
