Question

A curve of radius 68 m is banked for a designed speed of 85km/h. If the coefficient of static friction is 0.30, at what range of speeds can a car safely make the curve? (You must show schematic and free-body diagrams, and apply Newton's 2nd law of motion.)

Answer #1

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 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 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 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...

If a car takes a banked curve at less than the ideal speed,
friction is needed to keep it from sliding toward the inside of the
curve (a real problem on icy mountain roads).

banked at 14.0°.

A car moving at 36 km/h negotiates a 140 m -radius banked turn
designed for 60 km/h .
What coefficient of friction is needed to keep the car on the
road?
Express your answer using two significant figures.

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...

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 curve of radius 20 m is banked so that a 1000 kg car traveling
at 60 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
0.2. Answer in units of...

If a car takes a banked curve at less than the ideal speed,
friction is needed to keep it from sliding toward the inside of the
curve (a real problem on icy mountain roads). (a) Calculate the
ideal speed to take a 105 m radius curve banked at 15°. Correct:
Your answer is correct. m/s (b) What is the minimum coefficient of
friction needed for a frightened driver to take the same curve at
30.0 km/h?
