Question

A sports car with a mass of 1140 kg is rounding a flat, unbanked curve of radius 524 m at a constant speed of 60 m/s . If the car does not skid, what is the static frictional force between the tires and the road?

2610 N

7830 N

8190 N

1570 N

Answer #1

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...

The friction between the tires of a car and a flat road provides
the centripetal force for a
turn. For a 1800 kg car travelling at 25 m/s on a curve of radius
100 m:
a. Calculate the normal force on the car from the road.
b. Calculate the centripetal force required to turn the car
safely.
c. Calculate the minimum coefficient of static friction between the
tires and road for the car
to turn safely.
d. Ice on the...

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 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 930 kg sports car collides into the rear end of a 2300 kg SUV
stopped at a red light. The bumpers lock, the brakes are locked,
and the two cars skid forward 3.1 m before stopping. The police
officer, knowing that the coefficient of kinetic friction between
tires and road is 0.80, calculates the speed of the sports car at
impact.
What was that speed?

A 890-kg sports car collides into the rear end of a 3000-kg SUV
stopped at a red light. The bumpers lock, the brakes are locked,
and the two cars skid forward 2.5 m before stopping. The police
officer, estimating the coefficient of kinetic friction between
tires and road to be 0.80, calculates the speed of the sports car
at impact.
What was that speed?

A 920 kg sports car collides into the rear end of a 2300 kg SUV
stopped at a red light. The bumpers lock, the brakes are locked,
and the two cars skid forward 2.8 m before stopping. The police
officer, knowing that the coefficient of kinetic friction between
tires and road is 0.31, calculates the speed of the sports car at
impact. What was that speed?

A 800-kg sports car collides into the rear end of a 2900-kg SUV
stopped at a red light. The bumpers lock, the brakes are locked,
and the two cars skid forward 2.9 m before stopping. The police
officer, estimating the coefficient of kinetic friction between
tires and road to be 0.80, calculates the speed of the sports car
at

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 car has a velocity of 40.0 m/s and a mass of 2000.0 kg. A
curve has a radius of 80.0 m. The curve has a bank angle of 30.0
degrees. The coefficient of friction between the tires and the road
is 0.92. Would the car have enough Fc to make it around the
curve?
