A water wheel has a radius of 9 feet. The wheel is rotating at 5 revolutions per minute. Find the linear​ speed, in feet per​ mi
guajiro [1.7K]

Answer:

90\pi\text{ ft/s}\approx282.74\text{ ft/s}

Step-by-step explanation:

Refer to physics equation v=\omega r, where \omega is angular velocity.

Angular velocity's SI unit is rad/s. Convert rev/min to rad/s:

\displaystyle 5\text{ rev/min}=5\cdot \frac{1}{60}\cdot 2\pi\approx 0.524\text{ rad/s}

Now substitute \displaystyle\omega=\frac{1\pi}{6} and r=9 into v=\omega r:

\displaystyle v=\frac{1\pi}{6}\cdot 9=\frac{3}{2}\pi\text{ ft/s}=\boxed{90\pi\text{ ft/s}}
