Question

OPENING PROBLEM

Andrew is watching a Ferris wheel rotate at constant speed. There are many lights around the Ferris wheel, and Andrew watches a green light closely. The height of the green light after t seconds is given by H(t) = 10 sin((t-25)) + 12 metres.How long does it take for the wheel to complete a full circle?

Answer 1

How long does it take for the wheel to complete a full circle?

Height of the green light after t seconds is given by H(t) = 10 sin((t-25)) + 12 metre

period = amount of time it takes to complete 1 cycle

period = 2(pi)/b

b = 1

period=2pi/1

period=amount of time it takes to complete 1 cycle = 2pi
