Car A is constantly 2 feet from the center of the race track and travels at a constant speed.
Car A is constantly 2 feet from the center of the race track and travels at a constant speed. The angle with a terminal ray passing through Car A sweeps out 1 radian per second.
a. How many radians 0 does the angle sweep out in t seconds?
b. Define a function f that determines Car A'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.
c. The angle with a terminal ray passing through Car A must sweep out 2 radians to make one full rotation, and we know it sweeps out 1 radian per second. How many seconds will it take Car A to complete one full lap?
d. The graph of the function f is shown below.
