Question

In the case of a completely inelastic collision of two objects with the same mass and the velocity given for only one of the objects before the collision, given the velocity after the collision, determine the velocity of the 2nd object before the collision.

Please explain in simplest terms and give an example using units given.

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.

5 You have two objects with the same mass and they are going to
collide with respect to each other. Estimate the ratio between the
total kinetic energy associated with the two objects before and
after the collision. Assume that the collision was a perfectly
inelastic collision and that one of the two objects was moving with
a certain velocity and the other was at rest before the
collision.

One object is at rest, and another is moving. The two collide in
a one-dimensional, completely inelastic collision. In other words,
they stick together after the collision and move off with a common
velocity. Momentum is conserved. The speed of the object that is
moving initially is 30 m/s. The masses of the two objects are 3.0
and 7.6 kg. Determine the final speed of the two-object system
after the collision for the case (a) when the large-mass object is...

Hi, please make up an example that matches this description
Inelastic rotational 'collision' (analog of linear inelastic
collisions): given initial rotational velocities of two objects, as
well as enough information to determine moments-of-inertia,
determine final rotational velocity, as well as heat generated in
'collision' when they 'collide' (e.g., hit each other and form a
composite object). To do this, you will have to first calculate the
final angular velocity of the composite object, using conservation
of angular momentum, then calculate...

Two objects moving in the positive x direction have a perfectly
inelastic collision. The first object has a mass of 12 kg and a
velocity of 4 m/s. The second has a mass of 7 kg and a velocity of
1 m/s. (a) What is the velocity of the center of mass of the
system? (b) What are the velocities of the masses in the center of
mass frame? (I.e., imagine that you are moving with a velocity
v cm....

1.Imagine two balls colliding on a billiard table that is
frictionless. Decide which statement is correct and explain why:(a)
The total momentum of the system that contains only one of the two
balls is the same before and after the collision.(b) The total
momentum of the system that contains both of the two balls is the
same before and after the collision.
2.One object is at rest, and another is moving. The two collide
in one-dimensional, completely inelastic collision. In...

6) An object of mass 1.10 kg makes a completely inelastic
collision with an object of unknown mass at rest. If 60% of the
kinetic energy is lost, what is the unknown mass?

a) Two objects with the same mass move toward each other with
the same speed and experience a head-on elastic collision (angle =
180o). Will their final velocities be the same? Why?
b)Two objects moving toward each other (angle = 180o)
with different momentums produce an inelastic
collision. In what condition will both objects move to the left
after the collision.

Two rubber objects undergo a collision that we will approximate
as being elastic. The first object has mass 12.0 kg, and the second
object has mass 12.0 kg. Before the collision, the first object is
traveling at 4.00 m/s and the second object is traveling at -4.00
m/s (negative meaning in the opposite direction).
What is the velocity of the second object, after the
collision?

Consider a perfectly elastic collision between two objects of equal
mass. Object 1 is initially moving with a velocity v = 3.04 m/s
while object 2 is at rest. What are the final velocities after the
collision? Enter the final velocity of object 1 first.
