Homework Statement

The angular velocity of the ferris wheel with a diameter of 18m is pi/24 radians/s. How would that compare to m/s?

Homework Equations

v=(2pi(r))/360

The Attempt at a Solution

2pi(9)/360
=0.157m/s

You know the circumference and you should know how find how long it will take to make one revolution.
Circumference (m)/ time for revolution (sec)= speed m/sec.

 

[xcortz]

it takes 0.8mins to make one revolution

 

[RUber]

Right, so what do you get for speed in m/sec?

 

[xcortz]

Right, so what do you get for speed in m/sec?

would that be 1.178m/s?

because 2pi(9m)/48s

Looks good.
