Maximum - ? km/h

Answer #1

A curve of radius 70 m is banked for a design speed of 100 km/h
.If the coefficient of static friction is 0.39 (wet pavement), at
what range of speeds can a car safely make the curve? [Hint:
Consider the direction of the friction force when the car goes too
slow or too fast.]

A curve of radius 70 mm is banked for a design speed of 85 km/h
.
If the coefficient of static friction is 0.40 (wet pavement), at
what range of speeds can a car safely make the curve?
[Hint: Consider the direction of the friction force when
the car goes too slow or too fast.]
Express your answers using two significant figures separated by
a comma.
vmin, vmax = ????? km/h

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.)

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 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...

If a curve with a radius of 81 m is properly banked for a car
traveling 67 km/h , what must be the coefficient of static friction
for a car not to skid when traveling at 82 km/h ?

If a curve with a radius of 82 m is properly banked for a car
traveling 75 km/h , what must be the coefficient of static friction
for a car not to skid when traveling at 100 km/h ?

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 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 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...
