Answer #1

Car #1 with a mass of 1.50 x 103 kg is travelling east at a
speed of 25.0 m/s. It collides in the middle of an intersection
with Car #2 which has a mass of 2.50 x 103 kg and enters the
intersection travelling north at a speed of 20.0 m/s. (a) Find the
magnitude and direction of the velocity of the wreckage, assuming
that after the collision the two cars stick together and that
frictional forces can be neglected....

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 having mass M1= 1000 Kg moving
initially at V1i= 60 m/s collides with
a car having mass M2= 3000 Kg that was
moving initially at V2i = 20m/s. After
the inelastic collision, the cars stick and move together. The
final velocity of the two cars just after collision is
Vf =_______ m/s
Part A
40
20
60
30
Part B
If the collision time is t = 0.25 seconds, the
force exerted on the car having mass
M2= 3000...

A railroad car of mass 22 500 kg is traveling east 5.50 m/s and
collides with a railroad car of mass 30 000 kg traveling west 1.50
m/s. Find the velocity of the railroad cars that become coupled
after the collision.

A ball of mass 2 kg is moving with a velocity of 12 m/s collides
with a stationary ball of mass 6 kg and comes to rest. calculate
the velocity of the 6 kg ball after the collision. (both balls are
elastic)

7. Ball A with mass 0.85 kg is rolling at 3.5
m/s [N] when it collides with stationary Ball B with mass 1.15 kg.
After the collision, Ball A is moving 2.4 m/s [N40ºW]. Find the
velocity of Ball B after the collision.

a
1.2 kg ball moving with a velocity of 8.0m/s collides head on with
a stationary ball and bounces back at a velocity or 4.0 m/s. If the
collision is perfectly elastic, calculate (a) the mass of the other
ball (b) the velocity of the other ball after the collision (c) the
momentum of each ball before and after the collision (d) the
kinetic energy of each ball before and after the collision

Car A of mass 1,274 kg is traveling east at 13.2 m/s when it
collides with car B of mass 1,596 kg which is traveling at 14.6 m/s
at 71.4 degrees N of W. The two cars stick together after the
collision. What is the magnitude of the final velocity of the
cars?

A car with a mass of 2200kg, travelling at 60.0 km/h [E],
collides with a car of mass 1300 kg that is travelling at 30.0 kg/h
[E], and the two cars lock bumpers.
a) Calculate the velocity of the vehicles immediately after the
perfectly inelastic collision.
b) Calculate the total momentum of the two cars before and after
the collision.
c) Determine the decrease in kinetic energy during the
collision.

A 4.0 kg object is travelling south at a velocity of 2.8 m/s
when it collides with a 6.0 kg object travelling east at a velocity
of 3.0 m/s. If these two objects stick together upon collision, at
what velocity do the combined masses move?
