Riders on a Ferris wheel travel in a circle in a vertical plane. A particular wheel has radius 20 feets and revolves at the constant rate of one revolution per minute. How many seconds does it take a rider to travel from the bottom of the wheel to a point 10 vertical feet above the bottom? |

Answer» `R=2pi(ratios)/(min)` `Costheta=(R/2)/(R)` `Costheta=1/2` `theta=pi/3 radian` `T=theta/(2theta)=(pi/3)/(2pi)` `T=1/6` minutes `T=1/6*60=10 seconds`. |
