Question

A truck with a mass of 1430 kg and moving with a speed of 17.0 m/s rear-ends a 821 kg car stopped at an intersection. The collision is approximately elastic since the car is in neutral, the brakes are off, the metal bumpers line up well and do not get damaged. Find the speed of both vehicles after the collision in meters per second.

Vcar= ___ m/s

Vtruck= ___ m/s

Answer #1

A truck with a mass of 1420 kg and moving with a speed of 12.0
m/s rear-ends a 649 kg car stopped at an intersection. The
collision is approximately elastic since the car is in neutral, the
brakes are off, the metal bumpers line up well and do not get
damaged. Find the speed of both vehicles after the collision in
meters per second.
vcar = _______ m/s
vtruck = _______m/s

A truck with a mass of 1730 kg and moving with a speed of 14.0
m/s rear-ends a 743-kg car stopped at an intersection. The
collision is approximately elastic since the car is in neutral, the
brakes are off, the metal bumpers line up well and do not get
damaged. Find the speed of both vehicles after the collision.
vcar = ____m/s
vtruck = ____m/s

truck with a mass of 1840 kg and moving with a speed of 17.0 m/s
rear-ends a 732 kg car stopped at an intersection. The collision is
approximately elastic since the car is in neutral, the brakes are
off, the metal bumpers line up well and do not get
damaged.
(a)
Calculate the initial momentum of the truck (in kg m/s).
kg m/s
(b)
Calculate the final velocities (in m/s) for the truck and the
car.
vtf = m/s vcf...

A 801 kg car stopped at an intersection is rear-ended by a 1550
kg truck moving with a speed of 16.0 m/s. If the car was in neutral
and its brakes were off, so that the collision is approximately
elastic, find the final speed of both vehicles after the collision.

• A truck of mass 3500 kg moving at 15 m/s westward collides
with a 1700 kg car moving at 25 m/s eastward. The two vehicles are
enmeshed and move together. (a) Find their common speed and
direction. (b) Determine whether the collision is elastic.

An 1100-kg truck is stopped at a traffic light, when a 950-kg
car going at 24.0 m/s rear-ends it. If the two vehicles stick
together and move in the same direction the car had been going,
find: (a) the speed of the combined wreck just aftedre the
collision, (b) the amount of kinetic energy lost in the
collision.

1. A 1000.0 kg car is moving at 20 km/h. If a 2000.0 kg truck
has 25 times the kinetic energy of the car, how fast is the truck
moving? 2. A car of mass 1005 kg collides head-on with a parked
truck of mass 2010 kg. Spring mounted bumpers ensure that the
collision is essentially elastic. If the velocity of the truck is
15 km/h (in the same direction as the car's initial velocity) after
the collision, what was...

A large truck (mass 2,589 kg and speed 8.1 m/s) and a small car
(mass 1,166 kg and speed 23.8 m/s) going in opposite directions
collide head on. After the collision the two vehicles stick
together. Calculate their speed immediately after the
collision.

A car and a truck are both travelling with a constant speed of
20 m/s. The car is 10 m behind the truck. The truck driver suddenly
applies his brakes, causing the truck to decelerate at a constant
rate of 2 m/s^2. Two seconds later, the driver of the car applies
his brakes and just manages to avoid a rear-end collision.
Determine the constant rate at which the car decelerated.

A 1,200-kg car traveling initially with a speed of
25.0 m/s crashes into the rear of a 9,000-kg truck moving in the
same direction at 20.0 m/s. The velocity of the car after the
collision is 17.5 m/s. a) What is the velocity of the truck right
after the collision? b) How much mechanical energy is lost in the
collision?
