The height h(t) of a ferris wheel car above the ground after t minutes (in metres)...

Transcribed Image Text:

The height h(t) of a ferris wheel car above the ground after t minutes (in metres) can be 15.55 +15.24 sin(8πt). This ferris wheel has a diameter of 30.48 metres, and turns in an anticlockwise direction. modelled by: h(t) = (i) A person gets into a car on a platform at t = 0. What is the height of the platform above the ground? [1 marks] (ii) How long will it take for this passenger's car to first be at a height of 1 metre above the ground? HINT: Drawing diagrams using the unit circle may be of benefit in making sense of your solution steps.
