Question

A car merges onto the freeway on a banked curve. The car maintains a constant velocity 푣 while driving on the curve, which is banked at angle theta and has a radius of curvature R. The car has mass m and the coefficient of static friction between the car’s tires and the road is meu(s). What is the maximum and minimum speed that the car can go around the banked curve without slipping? Hint: The car tends to slip up if the car is going too fast or slip down if the car is going too slow. How do the maximum and minimum speeds change with decreasing angle theta? Do you think that banking a curve increases drivers’ safety? c. What is the only speed that the car can go around a banked curve in the absence of friction (i.e. static friction = 0)?

Answer #1

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...

A road with a radius of 75.0 m is banked so that a car can
navigate the curve at a speed of 15.0 m/s without any friction. If
the banking angle is reduced to zero when a car is going 20.0 m/s
on this curve, what minimum coefficient of static friction is
needed if the car is to navigate the curve without slipping?

A car rounds a 50 meter radius curve that is banked such that a
car rounding it does not need friction at a speed of 12 m/s. What
is the bank angle of the road?
The coefficient of kinetic friction between the tires and the
road is 0.5 and the coefficient of static friction between the
tires and the road is 0.8. If the same road were flat (instead of
banked), determine the maximum speed with which the coar could...

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 BMW is going around a banked curve in the road. It is part of
a circle with radius 125 m . An automobile that goes around the
curve with speed 20 m/s does not require any friction force to not
slip, but this BMW is going around the curve at 38.8 m/s. What's
the smallest value the coefficient of friction (between the tires
of the BMW and the road) that can be without any slipping?
Answer= .64 **But, How?**

A 1840-kg car travels on a banked, horizontal curve of diameter
250 m. Find the maximum safe speed if the coefficient of friction
between the tires and the road is 0.75 and the banking angle is 5.0
degrees. Additionally, what net force does the car experience in
this case?

A curve of radius 20 m is banked so that a 1100 kg car traveling
at 30 km/h can round it even if the road is so icy that the
coefficient of static friction is approximately zero. The
acceleration of gravity is 9.81 m/s 2 .
Find the minimum speed at which a car can travel around this
curve without skidding if the coefficient of static friction
between the road and the tires is 0.3. Answer in units of m/s.

A curve of radius 90 m is banked for a design speed of 80 km/h.
If the coefficient of static friction is 0.30 (wet pavement), at
what range of speeds can a car safely make the curve?
Minimum- ? km/h
Maximum - ? km/h

A car is on a banked curve
Angle is 13 degrees with r = 150.
Static fric = 0.35
What is the max speed and minimum speed it can make this
curve?

A 1000-kg car is traveling around a curve having a radius of 100
m that is banked at an angle of 15.0°. If 30m/s is the maximum
speed this car can make the curve without sliding, what is the
coefficient of friction between the road and the tires?
