The angle turned is obtained as 3.77 rads.

<h3>What is the angle of rotation?</h3>

We have the following information about the disk;

velocity 1= 7200 RPM

velocity 2 = 0 RPM

time taken = 0.01 seconds

We must convert from RPM to rad/s using the relation;

2π·7200/60 = 754 rad/s

Using;

θ = ωavt

θ = (754 rad/s + 0 rad/s)/2 * 0.01 seconds

θ = 3.77 rads
