Hello. I was wondering if anyone could help me with this problem. You'll probably think it is easy, but oh well :smile:.


begin to explore aspects of angular velocity/and linear velocity and how tires affect them.


Car Type Tire Type Tire Diameter-inches
Ford Taurus 215/60-16 26.16
Chevy Camaro 235/55-16 26.18
Dodge Dakota 255/55-17 28.04

#1. Find the speed of each car in mph when the wheels are turning at 800rpm.

Ok, my question is what formula do I use that includes the Tire type?


thanks
Grant

You'll need to use the diameters given to find the speed of the outer edge of the wheel at 800rpm. I don't think you need to know the tire types. In fact I don't have a clue what the tire type means, but I can figure out the speeds of those cars!
