In days gone by, people used oxen to pull giant stone wheels around a track to grind wheat into flour. The wheels were extremely heavy, and had a radius of 2.0 meters. The wheel would rotate 8.5 times each minute (8.5 RPM) and the ox would be worked for 4 hours before being allowed to rest and replaced with another oxen.

a. Find the angular velocity in radians/second b. Find the tangential velocity

c. Find how far the heavy wheel traveled in 4 hours
