Answer: centripetal acceleration
Equals 18350m/s²
Explanation: Centripetal acceleration is given as v²/r
Where v is Velocity measured in rad/s and r is radius
But v= w*r
Therefore,
C.acceleratn = w²*r²/r
So we have
C.accelertn = w²*r
Our w is given as 1200 rev/min so we have to convert to rad/sec
1rad/sec equals 9.5rev/min
Therefore,
1200rev/min = 1200/9.5 rad/sec
w=126.32rad/sec
r = diameter/2
r = 2.3/2 =1.15m
Let's now calculate our centripetal acceleration = w²*r
= {126.32rad/sec}² *1.15
=18350m/s²
