Some amusement parks have a double Ferris wheel, which consists of two vertically rotating wheels that are attached to each other by a bar that also rotates. There are eight gondolas equally spaced on each wheel. Riders experience a combination of two circular motions that provide a sensation more thrilling than the classic single Ferris wheel. In particular, riders experience the greatest sensation when their rate of change in height is the greatest. • Each of the two wheels is 6 min diameter and revolves every 12 s. • The rotating bar is 9 m long. The ends of the bar are attached to the centres of the wheels. • The height from the ground to the centre of the bar is 8 m. The bar makes a complete revolution every 20 s. • A rider starts seated at the lowest position and moves counterclockwise. • The bar starts in the vertical position.
d) What is the maximum height reached by the rider? When does this occur? e) What is the maximum vertical speed of the rider? When does this occur?
