each angular velocity??

each linear velocity??

- trig -
**Reiny**, Tuesday, June 11, 2013 at 6:42pmangular velocity:

1st wheel : 2π rad/30 sec

= π/15 rad/sec

2nd wheel : 2π radians/15 sec

= 2π/15 rad/sec

linear velocity

1st wheel:

circumference = 2π(20) = 40π ft

linear velocity = 40π/30 ft/sec

= 4π/3 ft/se

2nd wheel:

circumf = 20π

linear vel. = 20π/15 ft/sec = 4π/3 ft/sec
