A grindstone spinning at the rate of 12 rev/s has what approximate angular speed?Select one:a.3.2 rad/sb.52 rad/sc.26 rad/sd.75 rad/s
Question
Solution 1
The angular speed can be calculated using the formula:
ω = 2πf
where: ω is the angular speed, f is the frequency (in revolutions per second).
Given that the grindstone is spinning at a rate of 12 rev/s, we can substitute this value into the formula:
ω = 2π * 12
