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{ = }(100655.8)/(1)\text{ = 100655.8 ft/min} \\ \end{gathered}`
`\begin{gathered} a)\text{ Angular velocity = }(v)/(r)\text{ = }(100655.8)/(6) \\ =\text{ 16776 rev/min} \end{gathered}`
