# Rotational Motion, angular velocity

## Homework Statement

Two people are on a ride where the inside cars rotate at constant angular velocity three
times the constant angular velocity of the outer cars. If the two cars are in line at t = 0,
and moving at 3ω and ω respectively, at what time will they next pass each other?

## The Attempt at a Solution

What variable n represent?

Look at the clock at noon when the hour and minute hand are at top of each other. When will the next when the minute hand pass hour hand?

I think it is "pi".

thanks. Old eyes need reading glasses.

Do tell us how you tried it out, its much easier to help then

As a basic hint, think about the relative angular velocity of the two objects.

welcome to pf!

hi jimla! welcome to pf!
If the two cars are in line at t = 0,
and moving at 3ω and ω respectively …

ok, now translate that into (two) equations

what do you get?
