The blades on a model windmill take 4 seconds to make a full rotation. At the lowest point, the tip of the blade is Now work on your Key Questions in the online submission tool. 0.5 m off the ground, and at the highest point the tip of the You may continue to work at this task over several sessions, blade is 2.5 m off the ground. but be sure to save your work each time. When you have answered all the unit's Key Questions, submit your work to the ILC. Sketch a graph of height against time to show the distance between the tip of the blade and the ground for two complete rotations. At time zero, the blade is (20 marks) pointing straight down (closest to the ground). Clearly 56. a) Determine the period, amplitude, and phase shift of label the scale on both axes. (3 marks) f(x) = 30082 x - -|+ 1 (3 marks) by List the five critical points for the first cycle. (3 marks) () Use this information to sketch the graph of f(x) for two complete cycles. Determine _ wave and starting point. Clearly label the scale on both axes. (3 marks) 57. Determine an equation using a transformation of y = sinx that models water depth at the Bay of Fundy. This is the graph you first saw in the introduction to this lesson. (4 marks) b) Determine an algebraic equation relating the height (h) in metres of the tip of the blade above the ground at time (t) in seconds. (4 marks) Now go on to Lesson 14.
