The relationship between the magnitude of the force of tension and the force of friction is; Ff = (r/R)Ft
<h3>What is Rotational Acceleration?</h3>
We are given;
mass of spool = M
Radius = R
moment of inertia = I.
Now, the spool is not moving and as such;
r < R which means there is net torque = 0
Thus;
Ff × R = Ft × r
>> Ff = (r/R)Ft
Finally, the angular acceleration is expressed as;
α = a/R

The endothermic energy is released when the bond breaks between the atoms. The thermal kinetic energy is stored between the bonds of the nitroglycerin molecule.
<h3>What is Thermal kinetic energy?</h3>
Thermal energy is the total of the kinetic and the potential energy. The kinetic energy is the energy possessed by the object respective to its motion.
The potential energy is the stored energy with respect to the position of the object. The combination of kinetic and potential energy makes the thermal energy and is in the form of heat.
Therefore, the release of the heat from bonds indicates thermal kinetic energy.
