Question

a truck m2=3500kg collides with a stationary car
m1=1700kg. after collision, both vehicle move together with speed
+1.5m/s

a.what type of collision is this, and what physical quantity is
conserved?

b.calculate initial velocityof truck in km/h

c. what is the change ib kinetic enegy of system?

d.what happened to energy lost in collision?

Answer #1

Object 1, m1 = 3kg, collides and permanently sticks together
with a stationary second object, m2 = 2kg. After the collision,
they bounce off a moving third object, m3 = 2kg. If v1,i = +3m/s,
v3,i = −2m/s, and object 3 bounces off at twice the speed it comes
in, what are the final velocities of m1 and m2? Note that m1 and m2
are still stuck together.

A 4.34-kg toy car with a speed of 4.13 m/s collides with a
stationary 1.00-kg car. After the collision, the cars are locked
together with a speed of 3.6 m/s. How much kinetic energy is lost
in this 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?

1500-kg car moving at 16.00 m/s suddenly collides with a
stationary car of mass 1000 kg. Time of collision is .02 secs
e. What is the average force acting on the stationary car by the
moving car during the collision?
f. What is the total kinetic energy before the collision?
g. What is the total kinetic energy after the collision?
h. What is change in momentum?
i. What happens to the lost kinetic energy? Explain clearly
j. Is this an...

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 train car with mass m1 = 550 kg is moving to the
right with a speed of v1 = 8.5 m/s and collides with a
second train car. The two cars latch together during the collision
and then move off to the right at vf = 5.2 m/s.
What is the mass of the second train car? kg Submit 3) What is
the change in kinetic energy of the two train system during the
collision?

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 car, mass m1 is moving to the right on a frictionless air
track. It collides with a second car, mass m2, which is initially
at rest. Which of the following statements are true? (If A and E
are true, and the others are not, enter TFFFT).
A) If car 1 is much lighter than m2, and the collision is
perfectly elastic, car 1 will continue heading to the right with
nearly its original speed after the collision.
B) If...

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.
