3.31 A Ferris wheel with radius Figure E3.31
14.0 m is turning about a horizontal
axis through its center (Fig. E3.31).
The linear speed of a passenger on the
rim is constant and equal to 6.00 m/s.
What are the magnitude and direction
of the passenger's acceleration as she
passes through (a) the lowest point in
her circular motion and (b) the high-
est point in her circular motion? (c)
How much time does it take the Ferris
wheel to make one revolution?
