Me : ) a ferris wheel at a carnival has a diameter of 62 feet. suppose it turns at a rate of 70 revolutions per hour. (a) find the angular speed of the wheel in radians per hour. (b) find the linear speed of a passenger in feet per minute. do not round any intermediate computations, and round your answer to the nearest whole number.,

Diameter of Ferris Wheel = 62 feet => r = 31 feet Rate of revolution = 70 rev per hr A. Angular speed of wheel in radians per hour is Rate of revolutions x 2pi radians Angular Speed = 70 x 2 x 3.14 = 439.6 radians B. Linear Speed = radius x angular velocity angular velocity = 439.6 / 60 = 7.33 So the linear speed = 31 x 7.33 = 227.12 feet/min

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
