Explanation / Answer

Given that

speed v=83 km/h=83*5/18=23.1 m/s

diameter D=79 cm

radius r=39.5 cm=0.395 m

basing on the concept of rotational dynamices

basing on the concept of centripetal force

acceleration a=v^2/r

basing on the concept of system of paraticles in rotational dynamices

angular acceleration =a/r=(v^2/r)/r

=v^2/r^2

now we find the angular acceleration

the angular acceleration =v^2/r^2=23.1^2/0.395^2

=3420.03 rad/s^2
