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

Sorry i don’t know what to do

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
