together after the collision. Find the velocity of the two objects
after the collision.

find v1 final

and

v2 final

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.

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.

Consider a perfectly inelastic collision, where
two objects collide with each other, and stick together. The net
external force on the system is 0.
m1 = 2 kg
m2 = 3 kg
v01 = 5 m/s
v02 = -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?

A block of mass m1 = 1.20 kg moving at v1 = 1.20 m/s undergoes a
completely inelastic collision with a stationary block of mass m2 =
0.500 kg . The blocks then move, stuck together, at speed v2. After
a short time, the two-block system collides inelastically with a
third block, of mass m3 = 2.60 kg , which is initially at rest. The
three blocks then move, stuck together, with speed v3. Assume that
the blocks slide without...

Consider object-1 of mass m1=652gram moving on the +X axis with
the velocity of v1=13.5 m/s. Object-1 collide with stationary
object-2 of mass m2=846gram on the X-axis. After collision, both
objects are moving X-axis. a) Consider the collision is inelastic,
and two objects combined into one object after the collision. Find
the velocity of the combined object after collision? Consider the
collision remains about 1.82ms. find the impulse acts on object-1
during the collision . Find the energy lost due...

A
bomb explodes into 3 pieces. First piece m1=1kg, moves at v1=2m/s
at 30 degree to the horizontal m2=2kg moves at v2=1.5m/s to the
right and m3=3kg moves at v3=4m/s at 45 degree below the
horizontal. What was the bomb's initial velocity(magnitude and
direction)?

Two-car, 2-D collision. Two cars with masses
m1 = 1200 kg and m2 = 1500 kg are approaching an
intersection. Car 1 has a velocity v1 = 15.0 m/s towards
the east and car 2 has a velocity v2 = 20.0 m/s towards
the north. The two cars reach the intersection at the same time and
collide and lock bumpers and after the collision travel as a single
wreckage.
(a) What is the magnitude and direction of their velocity after...

Consider an elastic collision in one dimension that involves
objects of mass m1=2 kg and m2=11.3 kg. The
larger mass is initially at rest, and the smaller one has an
initial velocity of 16 m/s. Find the final velocities of the two
objects after the collision.

An object of mass m1=5kg is moving with a speed of vli-12m/s and
collides with another object at rest, that has a mass m2=7kg. After
the clastie collision these two objects move with
different speeds. What is the speed of m1 and m2 after the
collision?

In the lab frame two masses, m1=10 kg and
m2=6 kg collide elastically in one dimension with
