Question

Consider a perfectly **inelastic** collision, where
two objects collide with each other, and stick together. The net
external force on the system is 0.

*m*_{1}= 2 kg*m*_{2}= 3 kg*v*_{01}= 5 m/s*v*_{02}= -4 m/s

a) What is their final velocity, after the collision, in m/s? Make sure you get the correct sign.

b) How much kinetic energy was lost in the collision, in Joules?

Answer #1

Two objects collide in a totally inelastic collision. Just
before the collision,
the objects have the following masses and velocities:
M1 = 4.5 kg, v1 = 1.5 m/s @ 140o. M2 = 1.5 kg, v2 = 1 m/s @
180o.
a) Find the velocity of the object after the collision.
b) How much kinetic energy was lost in the collision.

Two cars collide at an icy intersection and stick together
afterward. The first car has a mass of 1250 kg and is approaching
at 9.5 m/s due south. The second car has a mass of 550 kg and is
approaching at 17 m/s due west.Calculate the direction of the final
velocity, in degrees south of west, of the cars.What is the change
in kinetic energy, in joules, for the collision? (This energy goes
into deformation of the cars.)

Two cars collide at an icy intersection and stick together
afterward. The first car has a mass of 1050 kg and was approaching
at 9.00 m/s due south. The second car has a mass of 800 kg and was
approaching at 20.0 m/s due west.
(a) Calculate the final velocity of the cars. (Note that since
both cars have an initial velocity, you cannot use the equations
for conservation of momentum along the x-axis and y-axis; instead,
you must look...

A 2.84 kg block, traveling at a speed of 12.4 m/s, undergoes a
perfectly inelastic
collision with a 3.68 kg block which starts at rest.
a) Find the final speed of each block.
b) Calculate how much energy was lost in the collision (final
kinetic energy minus initial kinetic
energy). If you were unable to calculate the answer to part (a),
assume the final velocity is 5.00 m/s.
c) How much energy would have been lost if the collision were...

Two cars collide at an icy intersection and stick together
afterward. The first car has a mass of 1300 kg and was approaching
at 5.00 m/s due south. The second car has a mass of 900 kg and was
approaching at 23.0 m/s due west.
(a) Calculate the final velocity (magnitude in m/s and direction
in degrees counterclockwise from the west) of the cars. (Note that
since both cars have an initial velocity, you cannot use the
equations for conservation...

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...
