In the sport of roller derby, players must pass a Minimum Skills test, in order to be allowed to participate in bouts. In one
part of the test a skater must get 27 laps around the track in 5 minutes.
Auntie Matter is a skater for the Reservoir Dolls, a roller derby team in Madison, Wisconsin. She is testing today to show
that she can get her 27 in 5. Auntie studies physics, and she decides to determine in advance the minimum centripetal
acceleration she will need in order to pass this test. Also, given that she knows the coefficient of friction of her wheels is
0.64 and her mass on skates is 67 kg, she decides to find the maximum number of laps she could get before losing friction
and skidding off the track.
Auntie chooses to skate Path B, skating in a path that is as close to a circle as possible. Based on the dimensions of a standard roller
derby track, this circle will have a radius of 16.3 meters. How many meters will Auntie have to travel in order to do 27 laps? (Please
provide an answer before moving to the next part.)
The total distance Auntie will have to travel is m
