Tangential speed

  • #1

Homework Statement


I thought this would be an easy question for me, but I cant figure it out.
"What is the tangential speed of a passenger on a Ferris wheel that has a radius of 10 meters and rotates once every 30 seconds?"

Homework Equations



Tangential speed = rotational speed x radial distance


The Attempt at a Solution



Tangential speed = 2RMP x 10 meters
= 20......what units? Not m/sec, not RPM.....
...But...
I figured the circumference is 62.83 meters x 2RPM = 125 meters per minute

With the information that it's 2RPM, you can very easily find the angluar velocity, ω. I'd use that as a starting point to finding the tangential velocity.

That doesn't help...
thanks though
