Answer:
The linear speed of the windmill is 32.682 ft/s.
Step-by-step explanation:
Given;
radius of the windmill, r = 26 ft
number of revolutions per minute, θ = 12 rpm
The angular speed of the windmill is given as;

The linear speed of the windmill is given as;
v = ωr
v = 1.257 rad/s x 26 ft
v = 32.682 ft/s
Therefore, the linear speed of the windmill is 32.682 ft/s.
