Question

A 1000 kg car rounds curve of radius 75 m banked at an angle of 15 degree, if the car is traveling at 100 km/h, will a friction force be required? If so, how much and what direction?

Answer #1

A 1600 kg car rounds a curve of radius 70 m banked at an angle
of 12°. If the car is traveling at 84 km/h, will a friction force
be required?
Yes friction force will be required, how much force?

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 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...

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?

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 ?

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...

An auto mobile traveling at 60 mph rounds a curve banked at 10
degrees. The radius of the curve is 200 ft. (a) What is the minimum
coefficient of friction that will keep the car on the road? (b)
What would the bank angle need to be in order for the car to stay
on the road without any friction?

Consider a train that rounds a banked curve with a radius of 189
m at a speed of 26.9 m/s. The track is inclined at an angle of 3.1
degrees towards the center of the curve. What is the frictional
force on a passenger on the train with mass 99.9 kg in order for
the passenger to remain stationary in the seat. Give your answer in
Newtons to at least 4 significant figures to avoid being counted
incorrect due to...

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...
