Question

Two cars have a head on- collision, bounce off each other, and their front end are smashed in. What time of collision is this?

a) Elastic collision where both momentum and energy is conserved.

b) A combination of elastic and inelastic collision where kinetic energy is conserved.

c) Inelastic collision where both momentum and energy is conserved.

d) A combination of elastic and inelastic collision where kinetic energy is not conserved.

Answer #1

When it comes to a car crash, which type of collision is better
for the health of the driver?
A) inelastic, because kinetic energy is not conserved
B) elastic, because momentum and kinetic energy are
conserved
C) inelastic, because momentum is conserved
D) both are equally safe

The bumpers on cars are designes so that cars will bounce off
each other during low-speed collisions, causing less damage.
Consider a bumper test where a 1840 kg car traveling to the right
at 1.55 m/s collides with a 1310 kg car going to the left at 1.10
m/s . The test results show that the heavier car's speed just after
the collision was 0.280 m/s in its original direction. You can
ignore any road friction during the test crash....

When cars are equipped with flexible bumpers, they will bounce
off each other during low-speed collisions, thus causing less
damage. In one such accident, a 1800 kg car traveling to the right
at 1.40 m/s collides with a 1450 kg car going to the left at 1.10
m/s . Measurements show that the heavier car's speed just after the
collision was 0.260 m/s in its original direction. You can ignore
any road friction during the collision.
A-What was the speed...

Hi, I'm doing an experiement where I compare elastic and
ineslatic collision on a straight track vs circular track with toy
cars and velcro for inelastic collision. My question is whether or
not momentum and kinetic energy is conserved in the circular track
for elastic and inelastic collision similiar to the straight track?
whats the difference between straight and circular track (like is
momentum not conserved in elastic collision ? etc.)? I know the
straight trac uses linear momentum and...

A rubber ball bounces off of a wall with an initial speed v and
reverses its direction so its speed is v right after the bounce. As
a result of this bounce, which of the following quantities of the
ball are conserved? A) the kinetic energy of the ball B) the
momentum of the ball C) both the momentum and the kinetic energy of
the ball D) None of the above quantities are conserved.

Suppose the two cars had rubber
bumpers in the front and back – similar to the bumper cars children
(of all ages!) ride at amusement parks. Also, suppose that the cars
are sturdy enough that the metal they are made of does not bend
during the collision. In this case, the cars would undergo a
perfectly elastic collision. Assume just like in the first
collision question that the SUV (initially moving to the right)
collides into the stationary smart car....

Two gliders are moving toward each other. Glider A has
a mass of 500 g and is moving with a velocity of 40 cm/s. Glider B
has a mass of 400 g and is moving with a velocity of -50 cm/s.
After a head-on collision, glider A moves with a velocity of 10
cm/s and glider B moves with a velocity of 50 cm/s.
A.) calculate the total initial and final momenta of the two
gliders. Determine whether linear momentum...

Elastic collisions: one at rest one moving, two colliding, both
initially moving the same direction.
Inelastic collisions: one at rest one moving, two colliding,
both initially moving the same direction.
Perfectly elastic collisions: one at rest one moving, two
colliding, both initially moving the same direction.
Was momentum conserved for all types of collisions you examined
in this experiment? If not, explain the cause of losing or
gaining momentum. Was total velocity conserved for all types of
collisions you examined...

Two cars approach an intersection at a right angle to each
other. If an inelastic collision occurs at the
intersection, determine the x component of the final momentum of
the combined vehicles. Car 1 of mass 865 kg approaches
the intersection from the left with a speed of 19.49
m/s. Car 2 of mass 1,121.17 kg approaches the
intersection from the south with a speed of 14.98 m/s.

a
1.2 kg ball moving with a velocity of 8.0m/s collides head on with
a stationary ball and bounces back at a velocity or 4.0 m/s. If the
collision is perfectly elastic, calculate (a) the mass of the other
ball (b) the velocity of the other ball after the collision (c) the
momentum of each ball before and after the collision (d) the
kinetic energy of each ball before and after the collision
