Question

A truck of mass 25947 kg is moving east at 63 km / h collides a car of mass 1271 kg moving west at 92 km / h. The Collision is completely inelastic and takes place on a frictionless road. Determine the fractional loss of kinetic energy after the Collision. Give an answer to one decimal place. Remember to add unit% after the numerical value.

Answer #1

A 2.0 kg mass moving to the east at a speed of 4.0m/s collides
head on in a comletely inelastic collision with a 2.0 kg mass
moving west at 2.0m/s. How much kinetic energy is lost during this
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 Cadillac of mass 2220 kg going east collides with a Geo of
mass 1210 kg headed north at 25 km/h on a level highway. The cars
remain tangled and slide to rest, producing a skid mark 35 m in
length. The coefficient of kinetic friction for the tires on the
road is 0.2.
How fast was the wreckage (tangled cars) moving right after
collision?
km/h
What is the direction of the skid mark?
° north of east
How fast...

A truck of mass 5000 kg was moving north at 45 km/h when it
collided with a car of mass 1250 kg moving east at 90 km/h. Find
the magnitude and direction of thre velocity of the vehicles after
the collision, assuming they became entangled and moved
together.

A car of mass 950 kg travelling north at 50 km/h collides with a
car of mass 1350 kg going south at 45 km/h in a completely
inelastic collision (i.e. they stick together). Determine the
velocity of the car/car combination immediately after the
collision. (North is the positive direction and south is the
negative direction.)
km/h

A 1200-kg sportscar is heading east at 75 km/h toward the east
when it collides with a 3350-kg truck traveling south at 50 km/h
and they stick together upon collison. Both vehicles were
driverless cars, so nobody was injured in this collision. What is
the direction of motion of the wreckage after collision?

Students in question are in the back of a 3200 kg moving truck
travelling east at 50 km/h. The students intend on ramming the
truck with their 2000 kg vehicle to force it to a stop. As the
moving truck moves through a nice open parking lot, they travel at
80 km/h directly southwest (50 degrees south of west) and collide
with the moving truck. Both vehicles become stuck together and move
off as one after the collision. Treat east...

an automobile of mass 1500 kg moving at 25 meters per
second collides with a truck of mass 4500 kg at rest. the car and
the truck bounce off each other completely elastically. what is the
final velocity of the truck after the Collision call the direction
of the automobile before the Collision positive

A ball of mass 2.5 kg moving east with a speed of 4.2 m/sec
collides head-on with a 1 kg ball initially moving at 1.7 m/sec to
the west. If the collision is elastic, what will be the speed and
direction of each ball after the collision?

A car with a mass 1500kg traveling East 10m/s collides with a
truck with a mass 2000kg traveling West at 12m/s. After the
collision, the two are stuck together.
A) Find the final speed.
B) How much kinetic energy was lost?
