A cyclist is riding a bicycle whose wheels have a radius of 12 inches. Suppose she is traveling at 24 miles per hour. (A useful fact: 1 Mile=5280 ft .)

(a) Find the angular speed of the wheels in radians per minute.
(b) Find the number of revolutions the wheels make per minute.

Respuesta :

Answer:

a.2010 rad/min

b.2412 feet/min

Step-by-step explanation:

We are given that

Diameter of wheel,d=2.4 feet

Radius,r=

a.Rate=320 rev/minute

1 rev= radian

320 rev/minute=

Where  

Angular speed=

b.Speed,v=
