Question

available until you signif Four toy racecars are racing along a circular race track. The cars start at the 3-o'clock position and travel CCW along the tracks t = 4.46 Car B is constantly 3 feet from the center of the race track and travels at a constant speed. The angle Car B sweeps out increases at a constant rate of 2 radian per second. a. How many radians does car B sweep out in t seconds? Preview b. Define a function g that determines Car B's distance to the right of the center of the race track (in feet) as a function of the number of seconds & since the start of the race. s(0) Preview c. Car B must sweep out 2 radians to complete one full lap, and we know it sweeps out 2 radian per second. How many seconds will it take Car B to complete one full lap? seconds Previcw
