Question
The table below give the velocity, in feet per second, of a rider on a Ferris
Wheel at an amusement part. The time, t, is measured in seconds after the
ride starts. The rider moves smoothly and the table gives the values for one
complete revolution of the wheel. The rider boards the Ferris Wheel at the
bottom.
