Answer:
The diameter of the bull-wheel is 3.82
Explanation:
Given that,
Velocity = 2.0 m/s
Angular velocity = 10 rev/m


We need to calculate the diameter of bull-wheel
Using formula of angular velocity


Put the value into the formula


The diameter of the bull-wheel



Hence, The diameter of the bull-wheel is 3.82 m.
