Question

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 as the positive x-direction here, and north as the positive y-direction.

a) Find the momentum of each vehicle before the collision

b) Find the magnitude and direction of the velocity of both vehicles after the collision

Answer #1

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 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 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?

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...

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 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 900 kg car moving East with speed of 20 m/s collides with a
1500 kg car moving North with speed of 15 m/s at an intersection.
Both cars stick together after collision. What is the speed and
direction of these two stuck cars immediately after this
collision?

pls answer as soon as possible! thanks.
A 3000 kg truck travelling at 50 km/hr strikes a stationary 1000
kg car, locking the two vehicles together.
A) What is the final velocity of the two vehicles?
B) How much of the initial kinetic energy is lost to the
collision?

A
120 kg lineman moving west tackles an 80kg football fullback moving
east at 8 m/s. After the collision, the 80kg fullback move east at
2m/s and the 120kg lineman moves east at 3m/s. What was the
velocity(speed and direction) of the 120kg lineman before the
collision ?

Problem 7.26 A 0.250-kg ice puck, moving east with a speed of
5.62 m/s , has a head-on collision with a 0.900-kg puck initially
at rest. Assume that the collision is perfectly elastic.
Part A What is the speed of the 0.250-kg puck after the
collision?
Express your answer to three significant figures and include the
appropriate units.
v1 =
Part B What is the direction of the velocity of the 0.250-kg
puck after the collision? What is the direction...
