Answer:
The answer is 1280m/s^2
Explanation:
Step one:
given
Angular acceleration of 20 rad/s^2
The radius of the disk is 20cm = 0.2m
angular speed is 16 rad/s
Required
The centripetal acceleration
Step two
The expression for the centripetal acceleration is
[tex]a_c = \frac{ \omega^2}{r}[/tex]
a_c =centripetal acceleration
v =velocity
r =radius
Substituting we have
[tex]a_c = \frac{ 16^2}{0.2}\\\\a_c = \frac{256}{0.2}\\\\ a_c = \1280m/s^2[/tex]
