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

<h3><em>Quartzite is made of the mineral quartz – a hard resistant mineral. Additionally, when the parent material (quartz-rich sandstone) undergoes metamorphic processes of heat and pressure, the resulting rock quartzite is harder than the sandstone due to an increase in density.</em></h3><h3><em>1.

As a driver that is approaching an about, it is very important to respect the drivers that are already in the about.
<h3>
What is an About?</h3>
An about is basically a junction that is circular in shape, in an about the vehicle at the left is given very high priority.
