A Ferris wheel at a carnival has a radius of 10 m and is 2 m above the ground. The Ferris wheel makes 2 rotations every 4 minutes. a) How many seconds will it take for the Ferris wheel to make one rotation? (write your answer in the first box below) b) If Gurpreet and Harpreet are riding the Ferris wheel and start at the bottom, write a sine equation modelling their height over time. Use h to represent their height above the ground, in metres, and t to represent the time elapsed, in seconds. (write your answer in the second box below) a) 60 seconds b) h(t)=-10sin(t-30)+12 a) 150 seconds b) h(t)=-10sin[3(t-10)]+4 a) 120 seconds b) h(t)=-10sin[3(t+30)]-12 a) 120 seconds b) h(t)=-10sin[3(t-30)]+12
