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.

Suppose we are looking at a collision of two masses in 1D. The
masses are m1 and m2, their initial velocities are V10 and V20 and
their final velocities are v1 and v2. Momentum is conserved in this
collision which means that it should be possible to express v2 in
terms of v1 and other constants.
a) determine the final speeds of m1 and m2 in terms of v1 and
other constants
b) determine the initial and final kinetic energies...

Suppose that we have two masses, m1 and m2, traveling at initial
velocities v1i and v2i . After they collide, they will have
velocities v1f and v2f . The collision will happen along a straight
line, and there are no external forces involved. Answer all
exercises.
Exercise 2
For the collision above what is are the initial and final
kinetic energies? Is kinetic energy conserved in the collision?
Exercise 3
Let m1 = 500 g, m2 = 500 g, v1i...

Two masses collide in an elastic collision,
with the following initial values:
m1 = 2 kg
m2 = 3 kg
v01 = 5 m/s
v02 = -4 m/s
Use the conservation rules, and algebra, what is the final
velocity of mass 1, vf1 in m/s?

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.

v2f

Two
gliders with different masses (m1 and m2) are placed on a
frictionless air track and given initial velocities v1i and v2i.
They elastically collide, bouncing off each other. (a) Determine
the equations for the final velocity of each glider. (b) For m1 =
0.51 kg, m2 = 0.98 kg, v1i=1.5 im/s, and v2i=-2.2 im/s, find v1f
and v2f.

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 inelastic collision between two spheres of
different masses, m1= 1kg and
m2=3 kg, in the +x direction. Ball M1 is
moving at speed,
v1=3.0ms, and ball 2
is moving towards ball 1 at speed, v2=1 kg.
1. What will happen to the velocities of the two balls after a
completely inelastic collision? Explain your
reasoning. Do NOT do any calculation yet. Use your physical
intuition and what know so far about collisions.
2. Which physical principles were used...

A block of mass m1 = 1.90 kg initially moving to the right with
a speed of 4.6 m/s on a frictionless, horizontal track collides
with a spring attached to a second block of mass m2 = 4.8 kg
initially moving to the left with a speed of 1.1 m/s.The spring
constant is 519 N/m.
What if m1 is initially moving at 3.4 m/s while m2 is initially
at rest? (a) Find the maximum spring compression in this case. x...

A bumper car with mass m1 = 114 kg is moving to the
right with a velocity of v1 = 4.7 m/s. A second bumper
car with mass m2 = 94 kg is moving to the left with a
velocity of v2 = -3.7 m/s. The two cars have an elastic
collision. Assume the surface is frictionless.

2)What is the initial velocity of car 1 in the center-of-mass...
