Question

A 1200 kg car traveling 15 m/s needs to stop in 0.8 seconds to avoid hitting a pedestrian. a.)What impulse must the car receive? b.) What average force does this mean must be applied? c.) What is the three-part name of this force? d.) If a typical tire has a coefficient of friction of 0.6, will the car stop in time?

Answer #1

A 1200 kg car moving at 5.3 m/s is initially traveling north in
the positive y direction. After completing a 90°
right-hand turn to the positive x direction in 4.1 s, the
inattentive operator drives into a tree, which stops the car in 260
ms. What is the magnitude of the impulse on the car
(a) due to the turn and (b) due
to the collision? What is the magnitude of the average force that
acts on the car (c)...

A car, 1110 kg, is traveling down a horizontal road at 20.0 m/s
when it locks up its brakes. The coefficient of friction between
the tires and road is 0.901. How much distance will it take to
bring the car to a stop?

The driver of a one ton car traveling at 126 km/hr
suddenly used his brake to stop before
hitting a stationary lorry ahead. After the brakes are applied, a
constant kinetic friction
force of magnitude 8 kilo Newton acts on the car. Ignore air
resistance. (a) At what
minimum distance should the brakes be applied to avoid a collision
with the other
vehicle? (b) If the distance between the vehicles is initially only
30.0 m, at what speed
would the...

Traveling at 40.2 m/s, a driver applies the brakes to his
fast-moving car and skids out of control on a wet concrete
horizontal road. The 2000 kg car is headed directly toward a
student waiting to catch a bus to campus who is standing 58.0 m
down the road. Luckily, Superman is flying overhead and surveys the
situation. Knowing that the coefficient of kinetic friction between
rubber and rough wet concrete is .800, he determines that friction
alone will not...

If a train car with a mass of 10,000 kg traveling at 50 m/s is
brought to a stop in 100m, what is the magnitude of the force that
stops it?

After applying breaks to stop at a stop sign, a 1000 kg car (C)
skids (wheels are locked) along the straight ﬂat road (R) for a
halt. The car was initially traveling at 15 m/s and it was brought
to a complete stop within 3 seconds. Assume, no air
resistance.
i. Using a force diagram and the deﬁnition of the work done,
identify if each force does positive, negative, or zero work on the
system of the “car and the...

A 3500-kg car traveling at 65 km/h skids and
hits a wall 3 seconds later. The coefficient of friction
between the tires and the road is 0.10. What is the speed
of the car in m/s when it hits the wall?
A. 15.11
B. 12.64
C. 6.29
D. 0.14
E. 4.88
F. 8.58

A 1060 - kg car moving at 8.80 m/s is
initially traveling north along the positive direction of a y axis.
After completing a 90° right-hand turn to the positive x direction
in 4.00 s, the inattentive operator drives into a tree,
which stops the car in 430 ms.
In unit-vector notation, what is the impulse on the car during the
turn?
+
In unit-vector notation, what is the impulse on the car during
the collision?

What is the...

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?

4. A 2144 kg car is traveling along a straight path at 31 m/s
(approximately 70 mph). The driver then
employs the braking system to bring the car to a complete stop
in 7.59 s. (You may assume the
acceleration is constant.)
A. Determine the magnitude of the force required to cause the
acceleration.
B. Name and describe (in detail) the force that caused the
acceleration.
C. Explain, in detail, how Newton’s First Law and Newton’s
Third Law apply to...
