Question

3. A circular racetrack has a radius of 500 meters. Cars start at a starting line and drive
clockwise around the track. At 1/3rd the distance of the track from the starting line is the
first checkpoint.
a. In radians, what angle needs to be travelled by the racers from the start to the first
checkpoint?
b. How much physical distance do the racers travel in part a?
c. The fastest car reaches the first checkpoint in 18.6 seconds. Over that time period,
what was their average angular velocity?
d. Over the time period in part c, what was the fastest car's average linear velocity?
e. Assuming the car keeps the same velocity as your answer to part d, what would its
centripetal acceleration be?
f. What force is causing this centripetal acceleration?
