The London ferris wheel has diameter450 feet and completes one revolution in 30 minutes. The wheel is boarded from a platform that is 12 feet above the ground. Calculate the angular velocity (in degrees per minute) of the ferris wheel. Sketch the graph of a person\'s height H above the ground with respect to time t over one revolution Find the formula for H(t) in minutes.

Solution

A. Angular velocity=theta/t

It completes one revolution or 360 degree in 30 mins

Therefore theta=360 and t=30 mins

Angular velocity=360/30=12 degree per minute
