Question

How do I solve for (a) angular velocity and (b) revolutions per minute?

Answer 1

Diameter = 12 ft

Radius r = Diameter/2 = 12/2 = 6 ft

Distance = 19mi 335.8 ft

= 19 x 5280 + 335.8

= 100320 + 335.8

= 100655.8 ft

$\begin{gathered} L\text{ inear velocity v = }\frac{Dis\tan ce}{\text{Time}}\text{ = }\frac{100655.8}{1}\text{ = 100655.8 ft/min} \\ \end{gathered}$$\begin{gathered} a)\text{ Angular velocity = }\frac{v}{r}\text{ = }\frac{100655.8}{6} \\ =\text{ 16776 rev/min} \end{gathered}$
