Question

The Daytona 500 stock car race is held on a track that is approximately 2.5 miles long, and the turns are banked at an angle of 31 degrees. It is currently possible for the cars to travel through the turns at a speed of 172 miles per hour. Assuming these cars are on the verge of slipping into the outer wall of the racetrack, find the coefficient of static friction between the tires and the track (assume the track is circular)

Answer #1

The Daytona 500 stock car race is held on a track that is
approximately 2.5 mi long, and the turns are banked at an angle of
31°. It is currently possible for cars to travel through the turns
at a speed of about 164 mi/h. Assuming these cars are on the verge
of slipping into the outer wall of the racetrack, find the
coefficient of static friction between the tires and the track.
(Assume that the track is circular.)

A curve at a racetrack has a radius of 600 m and is banked at an
angle of 7.0 degrees. On a rainy day, the coefficient of friction
between the cars' tires and the track is 0.50. Part A. What is the
maximum speed at which a car could go around this curve without
slipping? Give answer as vmax= and m/s

A race car drives at a speed of 20.0m/s around a circular track
banked inwards at an angle of 20.0o from the horizontal. The track
is icy, so there is no appreciable friction of the tires on the
track. Determine the radius of the track. Submit your answer in the
following form:
• List all the physical forces acting on the object. Which one
of them supplies a centripetal component?
• Give your numerical answer for the radius of the...

A race-car driver is driving her car at a record-breaking speed
of 225 km/h. The first turn on the course is banked at 15, and the
car’s mass is 1450 kg.
find :
a) Calculate the radius
of curvature for this turn.
b) Calculate the
centripetal acceleration of the car.
c) If the car
maintains a circular track around the curve (does not move up or
down the bank), what is the magnitude of the force of static
friction?...

An 800-kg race car can drive around an unbanked turn with
coefficient of static friction between the track and the car's
tires of 0.02. The turn has a radius of curvature of 150 m. Air
flowing over the car's wing exerts a downward-pointing force of 10
000 N on the car. Calculate the maximum speed without slipping.

A 890-kg race car can drive around an unbanked turn at a maximum
speed of 43 m/s without slipping. The turn has a radius of 150 m.
Air flowing over the car's wing exerts a downward-pointing force
(called the downforce) of 12000 N on the car. (a) What is the
coefficient of static friction between the track and the car's
tires? (b) What would be the maximum speed if no downforce acted on
the car?

A 770-kg race car can drive around an unbanked turn at a maximum
speed of 42 m/s without slipping. The turn has a radius of 160 m.
Air flowing over the car's wing exerts a downward-pointing force
(called the downforce) of 12000 N on the car.
(a) What is the coefficient of static friction
between the track and the car's tires? (b) What
would be the maximum speed if no downforce acted on the
car?

Chapter 05, Problem 22
A 780-kg race car can drive around an unbanked turn at a maximum
speed of 43 m/s without slipping. The turn has a radius of 180 m.
Air flowing over the car's wing exerts a downward-pointing force
(called the downforce) of 11000 N on the car.
(a) What is the coefficient of static friction
between the track and the car's tires? (b) What
would be the maximum speed if no downforce acted on the
car?

4. A designer plans to build a circular Indy 500 racetrack with
a bank angle of 12 degrees and it must keep cars moving at 150
miles per hour (242 km per hour) from sliding off the track even
when the track is slick. a) Draw a diagram showing all forces
acting on a racecar as it rounds the track. Neglect friction. b)
Choose an x-y coordinate system and write the components of the
forces. Why is the choice of...

A curve of radius 30 m is banked so that a 950-kg car traveling
at 25 miles per hour can round it even if the road is so icy that
the coefficient of static friction is approximately zero. You are
commissioned to tell the local police the range of speeds at which
a car can travel around this curve without skidding. Neglect the
effects of air drag and rolling friction. If the coefficient of
static friction between the snowy road...
