Two automobiles with equal mass approach an intersection. One vehicle is traveling eastward and the other vehicle is traveling northward. The vehicles collide and stick together. After impact they travel on the road and then travel on a gravel covered shoulder until both cars stop. Only the northward bound vehicle left skid marks at an angle of 55 degrees north of east. A police officer posted at the intersection clocked the eastward vehicle at 29 mph before impact. The northward bound car skid on the road for 25 ft and continued to skid on the gravel covered shoulder. What is the total distance, in feet, the two cars traveled after the collision? Assume us = 0.96 and uk = 0.85 for the road and us = 0.74 and uk = 0.65 for the shoulder.

Two cars approach an ice-covered intersection. One car, of mass
1.22 103 kg, is initially traveling north at 10.6 m/s. The other
car, of mass 1.66 103 kg, is initially traveling east at 10.6 m/s.
The cars reach the intersection at the same instant, collide, and
move off coupled together. Find the velocity of the center of mass
of the two-car system just after the collision.

Two particles approach each
other with equal and opposite speed v. The mass of one particle is
m, and the mass of the other particle is nm, where n is just a
unitless number. Snapshots of the system before, during, and after
the elastic collision are shown above. After the collision the
first particle moves in the exact opposite direction with speed
2.40v, and the speed of the second particle is unknown. What is the
value of n?

Two automobiles collide. One automobile of mass 1.13 x
103 kg is initially traveling at 25.7m/s [E]. The other
automobile of mass 1.25 x 103 kg has an initial velocity
of 13.8 m/s [W]. The vehicles become attached during the
collision
(a) Determine the magnitude and direction of the change in momentum
for each automobile in question 7.
(b) How are these two quantities related?
(c) What is the total change in the momentum of the two...

Two shuffleboard disks of equal mass, one orange and the other
yellow, are involved in an elastic, glancing collision. The yellow
disk is initially at rest and is struck by the orange disk moving
with a speed
vi.
After the collision, the orange disk moves along a direction that
makes an angle
θ
with its initial direction of motion. The velocities of the two
disks are perpendicular after the collision. Determine the final
speed of each disk. (Use any variable...

Two shuffleboard disks of equal mass, one orange and the other
yellow, are involved in an elastic, glancing collision. The yellow
disk is initially at rest and is struck by the orange disk moving
with a speed of 5.60 m/s. After the collision, the orange disk
moves along a direction that makes an angle of 36.0° with its
initial direction of motion. The velocities of the two disks are
perpendicular after the collision. Determine the final speed of
each disk.

A car with a mass of 980 kg is initially traveling east toward
an intersection with a speed of vc = 19.6 m/s
and a 1500 kg pickup is traveling north toward the same
intersection. The car and truck collide at the intersection and
stick together. After the collision, the wreckage (car and truck)
moves off in a direction of 35.0° above the x-axis.
Determine the initial speed of the truck and the final speed of the
wreckage.

A fuel consumption study is conducted for two types of
automobiles. One representative vehicle of each type is selected,
and the mileage performance is observed for 10 tanks of fuel in
each car. The data obtained, expressed in miles per gallon (mpg),
are as follows:
Car 1: 24.7 24.9 24.8 24.6 24.9 23.9 24.7 24.9 24.5 24.6
Car 2: 41.7 42.8 42.3 42.4 41.6 39.9 39.5 40.8 41.9 39.6
a) Using the appropriate distribution model and a 95% confidence
interval,...
