Question

Two masses collide in an **elastic** collision,
with the following initial values:

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

Use the conservation rules, and algebra, what is the final
velocity of mass 1, *v*_{f1} in m/s?

Answer #1

In the lab frame two masses, m1=10 kg and
m2=6 kg collide elastically in one dimension with
initial velocities v1=17 m/s and v2=3
m/s.
Calculate the kinetic energy of mass mn after the
collision, where n=2.
Enter responses using three significant digits.

Two skaters collide and embrace in an inelastic collision.
Alex's mass is 90 kg and his initial velocity is 1.5 m/s
i . Barbara's mass is 57 kg and her
initial velocity is 2.0 m/s j . After the
collision, the two skaters move together at a common velocity. Use
conservation of momentum to find their final speed.
A.
2.0 m/s
B.
1.7 m/s
C.
1.6 m/s
D.
1.5 m/s
E.
1.2 m/s

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 balls with masses of m1 = 10 kg and m2 = 50 kg undergo an
elastic collision with the first ball traveling east with a

velocity of 10 m/s. Find the speeds and the direction of the of the
two balls after the collision .

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?

Consider the collision of two identical particles. The masses of
the two particles are therefore equal m1=m2. The initial velocity
of particle 1 is v1 and particle two is initially at rest. After an
elastic head on collision, the final velocity of particle two is is
v'2 and is given by...

Two blocks of masses
m1 = 1.50 kg
and
m2 = 3.00 kg
are each released from rest at a height of
h = 4.40 m
on a frictionless track, as shown in the figure below, and
undergo an elastic head-on collision. (Let the positive direction
point to the right. Indicate the direction with the sign of your
answer.)
(a) Determine the velocity of each block just before the
collision.
(b) Determine the velocity of each block immediately after the...

A man of mass m1 = 64.5 kg is skating at v1 = 7.60 m/s behind
his wife of mass m2 = 53.0 kg, who is skating at v2 = 3.80 m/s.
Instead of passing her, he inadvertently collides with her. He
grabs her around the waist, and they maintain their balance.
(a) Sketch the problem with before-and-after diagrams,
representing the skaters as blocks.
(b) Is the collision best described as elastic, inelastic, or
perfectly inelastic? elastic inelastic perfectly inelastic...

Two blocks of masses m1 = 1.95 kg and m2 = 3.90 kg are each
released from rest at a height of h = 6.00 m on a frictionless
track, as shown in the figure below, and undergo an elastic head-on
collision. (Let the positive direction point to the right. Indicate
the direction with the sign of your answer.) Two blocks are on a
curved ramp similar in shape to a half-pipe. There is a flat
horizontal surface with opposite...
