Two cities lie due north of each other. City A has a latitude of 4530′ N.City B has a latitude of 62 8′ 22″ SAssume the earth has a radius of 4,000 miles. Determine the distance between the two cities. What would you do differently if theywere both N? A car wheel is 28 inches in diameter. Suppose the wheel turns at a rate of 4.8 revolutions per second. Find the angular velocity of the wheel in radians per second.Find the linear velocity of a point on the rim of the wheel which is 3 inches from the edge of the wheel in inches per second. ................
