You will need access to a wheel. It can be a car wheel, truck wheel, skateboard wheel, bicycle wheel or you may use a water bottle or can with a circular base. . Pick a point on the edge of the wheel meaning on its circumference that you can see from the side and measure the radius to that point. If you are using a bottle, pick a point on the edge of the circular base. . Estimate the time it takes to travel 10 feet at a constant speed. If you are using a bottle, roll it three feet at a constant speed and estimate the time it takes. . Use the time you estimated, the circumference and the distance to determine the speed in feet per second. . How many revolutions did it take to travel the distance? . Compute the speed in radians per second. This is angular speed. . What is the maximum height of the point you chose? . Construct a model using sine as a function of t in seconds for the vertical motion of the height above the ground of the point on the wheel or on the bottle. . Sketch the graph your model and circle two places where the point is one inch above the ground
