A race car rounds one end of a speedway. This end of the track is a turn with a radius r of approximately 187 ft.
If the track is assumed to be completely flat and the race car is traveling at a constant 71.00 mi/h around the turn, what is the race
car's centripetal (radial) acceleration ac?
ac =
ft/s²
Convert this result to SI units.
ac =
m/s²
What is the force responsible for the centripetal acceleration in this case?
friction
O gravity
O weight
normal

To keep from skidding into the wall on the outside of the turn, what is the minimum coefficient of static friction μ, between the
race car's tires and the track?
