Question

Two cars arriving at a T-intersection crash with each other. The first car has a mass of 1320kg and was traveling east at 80.0 km/h, the second car has a mass of 1740kg and was traveling north at 65.0km/h. If the collision is completely inelastic. with what speed are the wrecks moving after the collision and in which direction? You can ignore the effect of friction forces between the road and the cars during the collision.

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?

Two cars approach an ice-covered intersection. One car, of mass
1.21 X 10^3 kg, is initially traveling north at 12.1 m/s. The other
car, of mass 1.62 X 10^3 kg, is initially traveling east at 12.1
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.
magnitude: ______
direction: _____ north of east

Two identical cars collide at an intersection(m=1500kg). Car 1
is traveling east with a speed of 16 m/s and car 2 is traveling
north with a speed of 12 m/s. Immediately after the collison, car 1
travels with a speed of 8 m/s in a direction 60 north of east. The
cars do not stick together.
(a) What is the speed and direction of travel for car 2 after
the collision? (b) What is the change in kinetic energy of...

Two 200 kg cars approach an intersection. One car is traveling
east at 18 m/s. The second car is traveling north at 24 m/s. They
both collide and violently stick together. Immediately after the
collision they are moving

Four people, each has a mass of 65kg, get in a car with a mass of
1700kg.
1) What impulse is required to accelerate the car from rest to
a steady speed of 75 km/h on a flat road? Drag and friction can be
ignored.
2) Assume the car hits a stationary 600kg moose. The car was
still traveling at 75 km/h before the collision, and the collision
is perfectly inelastic, what is the speed of the car+moose (in
km/h)...

Two cars collide at an intersection. Car A, with a mass of 2000
kg , is going from west to east, while car B , of mass 1300 kg , is
going from north to south at 12 m/s . As a result of this
collision, the two cars become enmeshed and move as one afterward.
In your role as an expert witness, you inspect the scene and
determine that, after the collision, the enmeshed cars moved at an

Two dimensional collision problem. At an intersection, car A is
heading east at 90 km/h. Car A has a mass of 1500-kg. Car B is
heading south at 60km/h. Car B has a mass of 3000 kg. If they stick
together, what is the direction of motion of the cars after
collision?

Two cars are approaching an intersection on roads that are
perpendicular to each other. Car A is north of the intersection and
traveling south at 55 mph. Car B is east of the intersection and
traveling west at 50 mph. How fast is the distance between the cars
changing when car A is 20 miles from the intersection and car B is
15 miles from the intersection? (Round your answer to two decimal
places.)
____mph

Two cars collide at an intersection. Car A, with a mass of 2000
kg, is going from west to east, while car of mass 1500 kg, is going
from north to south at 15 m/s. As a result, the two cars become
enmeshed and move as one. As an expert witness, you inspect the
scene and determine that, after the collision, the enmeshed cars
moved at an angle of 52∘ south of east from the point of impact.
How fast...
