The front 1.20 m of a 1,450-kg car is designed as a "crumple
zone" that collapses to absorb the shock of a collision. (a) If a
car traveling 26.0 m/s stops uniformly in 1.20 m, how long does the
collision last? s (b) What is the magnitude of the average force on
the car? N (c) What is the magnitude of the acceleration of the
car? Express the acceleration as a multiple of the acceleration of
gravity. g

A car’s bumper is designed to withstand a 3.0–km/h (0.833–m/s)
collision with an immovable object without damage to the body of
the car. The bumper cushions the shock by absorbing the force over
a distance. Calculate the magnitude of the average force on a
bumper that collapses 0.220 m while bringing a 880–kg car to rest
from an initial speed of 0.833 m/s.

A 1000-kg car approaches an intersection traveling north at 20.0
m/s.
A car of equal mass approaches the same intersection traveling
east at 22.0 m/s.
The two cars collide at the intersection and lock together.
Ignoring any external forces that act on the cars during the
collision, what is the velocity ,aka, magnitude and direction, of
the cars immediately after collision?

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?

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 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?

Seat belts and air bags save lives by reducing the forces
exerted on the driver and passengers in an automobile collision.
Cars are designed with a "crumple zone" in the front of the car. In
the event of an impact, the passenger compartment decelerates over
a distance of about 1 m as the front of the car crumples. An
occupant restrained by seat belts and air bags decelerates with the
car. By contrast, an unrestrained occupant keeps moving forward
with...

A car of mass m = 1100 kg, moving with a velocity of 22.0 m/s,
skidded off the road hitting a tree that brought the car to rest in
2.0 s. Determine
(a) the impulse J imparted to the tree.
(b) the average force that acted on the tree
during collision.

Car A of mass 1,274 kg is traveling east at 13.2 m/s when it
collides with car B of mass 1,596 kg which is traveling at 14.6 m/s
at 71.4 degrees N of W. The two cars stick together after the
collision. What is the magnitude of the final velocity of the
cars?

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...
