Question

At a museum you can see the four cable lines that are used to pull cable cars up and down a hill. Each cable travels at a speed of 12.65 miles per hour, caused by a rotating wheel whose diameter is 9.5 feet. How fast is the wheel rotating? Express your answer in revolutions per minute. The angular speed of the wheel is revimin. (Round to two decimal places as needed.)

Answer 1

As relation between velocity and angular velocity is De VW T 1 1 Angular Velocity Angulor Velocity ---- linear endinus Velocity wm Give Ve 12.65 mileshwar *.1 miles = 5280 ft. so va 19.65 X5:280 ft > 1113.2 foties and 8= 95 ft. So angular speed fol = e = 1113.2 x2 min! To= 234.35 rev s mind
