1) A wheel of radius 160 cm is has an angular velocity of 400 radians per minute. What is the linear velocity of the wheel in kilometers per hour?
2) An average sized Frisbee has and area of 707 cm^2. Asuming that the typical throw velocity is 14 m/s, what is the angular velocity of the Frisbee?
3) In track races, runners typically line up in the "staggered start" configuration so that they each race for the same total distance. Assume that 5 runners are racing on a circular track and do not use the staggered start configuration. The track has a radius of 120 feet, and each runner's lane is 4 feet across. How much farther must runner 5 travel compared to runner 1?
