Four toy racecars are racing along a circular race track. The cars start at the 3-o'clock position and travel CCW along the track. t = Car D is constantly 5 feet from the center of the race track and travels at a constant speed. The angle Car D sweeps out increases at a constant rate of radian per second. a. How many radians does car D sweep out in t seconds? Preview j(t) = = = B Preview 0.88 b. Define a function j that determines Car D's distance to the right of the center of the race track (in feet) as a function of the number of seconds t since the start of the race. Preview c. Car D must sweep out 27 radians to complete one full lap, and we know it sweeps out i radian per second. How many seconds will it take Car D to complete one full lap? seconds d. Sketch the graph of the function j below.
