<p>You are in a car of a Ferris wheel. The wheel has a radius of 10 m and turns counterclockwise. Let the origin be at the centre of the wheel. Begin each sketch in parts a) and b) when the radius from the centre of the wheel to your car is along the positive x-axis.</p><p>Sketch a graph of your vertical displacement versus the angle through which you turn for one rotation of the wheel. Which function models the vertical displacement? Justify your choice.</p>
<p>The hour hand on a clock has a length of 14 cm. Let the origin be at the centre of the clock.</p><p>Sketch a graph of the horizontal position of the tip of the hour hand versus the angle through which the hand turns for a time period of 48 h, assuming the hour hand starts at 3.</p>
<p>Refer to question 1. Suppose each sketch in parts a) and b) begins when the radius from the centre of the wheel to your car is along the negative y-axis. Sketch a graph of your horizontal displacement versus the angle through which you turn for one rotation of the wheel. Which function models the horizontal displacement? Justify your choice.</p>
