mile at an average of 62.3 mi/h (27.8 m/s) on a track of planks set over railroad ties in the draft of a Long Island Railroad train. In 1985, a record was set for this type of “motor pacing” by Olympic cyclist John Howard who pedaled at 152.2 mi/h (68.04 m/s) in the wake of a race car at Bonneville Salt Flats. The race car had a modified tail assembly designed to reduce the air drag on the cyclist. Assume that the mass of bicycle plus rider is 72.3 kg in each case.
a) Draw a figure to represent the above problem. Let l and w represent the length and width of the rectangle, respectively.
b) Write the area A of the rectangular region as a function of I and in meters (not kilometers).
c) Write the area A of the rectangular regional as a function of w and in meters (not kilometers).
