Q3 Mathematical Methods Modelling with Functions Unit 4 - AOS 1

Question 3

7 marks

A Ferris wheel with a radius of 50 meters is rotating at a constant rate. The bottom of the wheel is 10 meters above the ground. A rider boards the wheel at its lowest point. It takes 4 minutes for the wheel to complete one full revolution.

Determine a piecewise function, $h(t)$, that models the rider’s height above the ground (in meters) at time $t$ (in minutes), considering the following scenario:

  • For the first 8 minutes, the wheel rotates at its normal speed.
  • From 8 minutes to 12 minutes, the wheel is stopped for maintenance.
  • After 12 minutes, the wheel resumes rotation, but at a rate 25% faster than its original speed.
