By definition, centripetal acceleration is given by:
[tex] a = \frac{v ^ 2}{r}
[/tex]
Where,
v: tangential disk speed
r: disk radius
Substituting values in the given equation we have:
[tex] a =\frac{3.3^2}{0.13}
a = 83.76923077
[/tex]
Rounding the result we have:
[tex] a = 83.8 \frac{m}{s^2} [/tex]
Answer:
The centripetal acceleration of the disc edge in m/s^2 is:
[tex] a = 83.8 \frac{m}{s^2} [/tex]
