The magnitude of the tangential acceleration of the hanging mass is 2mg/MR
<h3>
Tangential acceleration of the hanging mass</h3>
The tangential acceleration of the hanging mass around the pulley is determined from the principle of conservation of angular momentum as shown below;
τ = Iα
Where;
- I is the moment of inertia
- α is the angular velocity

Where;
- m is the hanging mass
- M is the mass of solid disk
The tangential acceleration is calculated as follows;

Thus, the magnitude of the tangential acceleration of the hanging mass is 2mg/MR

<u> </u> <span><span> No. Neutron stars are the remnants of very large stars that have supernova'd. Anything below 1.44 solar masses becomes a dwarf, anything above 5 solar masses becomes a black hole. Everything in between becomes a neutron star (or quark star, but it's not proven).</span>
