A 1600 kg sedan goes through a wide intersection traveling
from north to south when it is hit by a 2000 kg SUV traveling from
east to west. The two cars become enmeshed due to the impact and
slide as one thereafter. On-the-scene measurements show that the
coefficient of kinetic friction between the tires of these cars and
the pavement is 0.750, and the cars slide to a halt at a point 5.30
m west and 6.31 m south of the impact point.
Part A
How fast was sedan traveling just before the
collision?
Part B
How fast was SUV traveling just before the collision?

A 2100 kg truck is driving south through an
intersection at 40 mph when it crashes into a
1200 kg car that was driving east through the
intersection at 55 mph. The two vehicle stick
together in a sad, scary, twisted mess. What is the velocity
(both magnitude and direction) of the wreckage
immediately after the collision, before the vehicles have had any
time to slow due to friction?

An ambulance is traveling south at 50 m/s, away from a car that
is traveling north at 30 m/s. The ambulance driver hears his siren
at a frequency of 750 Hz. The velocity of sound is 343 m/s .
What frequency (in Hz) does the driver of the car hear the
siren?

police car is traveling south towards the intersection that a
robber’s car has just crossed traveling east. The robber’s car is
currently traveling 55 mph. The police car’s speed is currently 63
mph. How is the distance between the cars changing when the cop is
1.2 miles from the intersection, and the robber is .5 miles from
it? Be sure to answer in a complete sentence.

At a certain intersection, of all cars traveling north, the
relative frequency of cars continuing in the same direction is p.
The relative frequency of those turning east is q; all others turn
west.
Assume that drivers behave independently of one another. A small
group of n cars enters the intersection. For this group

turning west? Find the conditional distribution of X, the number of
cars turning east,...

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.

Joe leaves an intersection traveling west in his car. He is 20
feet from the intersection 4 seconds later. At the same time,
Joshua leaves the intersection heading north in his car so that his
position 4 seconds later is 26 feet from the intersection. If, at
that instant time, Joe's speed is 8 feet per second and Joshuas'
speed is 12 feet per second, find the rate at which the distance
between the two cars is changing to the...
