Question

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.

Answer #1

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

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...

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 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.

A car of mass m1 = 2000.0 kg is moving at speed v1i = 20.0m/s
towards East. A truck
of mass m2 = 5000.0 kg is moving at speed v2i = 10.0m/s towards
North. They collide at an
intersection and get entangled (complete inelastic
collision).
1. What is the magnitude and direction of the final velocity of the
entangled automobiles?
2. How much kinetic energy is lost in the collision. That is,
calculate the change in the
kinetic energy of...

A 1000-kg sports car is moving north at speed 15 m/s on a level
road when it collides with a 2000-kg truck driving east on the same
road at speed 10 m/s. The two vehicles remain locked moving
together after the collision at the origin of x-y plane. Assume
that the rolling friction is too small to be ignored.
A) explain what type of collision it is
B) indicate the vector momentum by showing its magnitude and the
(direction) angle...

A 1990 kg truck traveling north at 45 km/h turns east and
accelerates to 56 km/h. (a) What is the change in the truck's
kinetic energy? (b) What is the magnitude of the change in its
momentum?

A car has a mass of 2000 kg which was travelling east but now
has collided with truck with mass of 2500 kg which was travelling
north.
After the collision we see that the cars are stuck together and
have slid 7.7 meters northeast at a 40 degree angle.
The car driver claims the accident happened because the truck
was speeding; the truck driver claims the car was speeding. The
posted speed limit is 35 miles/hour.
Determine from the location...

A 1000-kg car moving north with a speed of 25.0 m/s collides
with a 2000- kg truck moving at an angle of 30° north of west with
a speed of 20.0 mjs. After the collision, the car and the truck
stuck together. What is the magnitude of their common velocity
after the collision?

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?
