Your car's speedometer works in much the same way as its odometer, except that it converts the angular speed of the wheels to a linear speed of the car, assuming standard-size tires and no slipping on the pavement. Part A If your car has standard 24-in.-diameter tires, how fast are your wheels turning when you are driving at a freeway speed of 35 mph

Respuesta :

Answer:

Speed will be 30810 rpm      

Explanation:

We have given diameter of the tire d = 24 inch

So radius [tex]r=\frac{d}{2}=\frac{24}{2}=12imch[/tex]

We have given linear velocity v = 35 mph

We know that linear velocity is given by [tex]v=\omega r[/tex]

[tex]35=\omega \times 12[/tex]

[tex]\omega =\frac{35}{12}\times \frac{63360}{60}=3080rad/min[/tex]

As we know that 1 mile = 63360 inch and 1 hour = 60 min
