Billiard balls of identical mass roll on a table, and we can ignore the small friction between the balls and the table. The cue ball travels east at a speed of 10 m/s and hits the 8 ball which is initially stationary. After the collision the cue ball travels at a speed of 3 m/s 10 degrees south of its initial eastward heading. What is the magnitude of the velocity of the 8 ball after the collision in m/s? Enter only the number to two significant figures.

We
observe a glancing collision between two billiard balls of the same
mass. The first ball is incident at a speed of 5.90 m/s, strikes
the second ball (initially at rest) and moves off with a speed of
5.06 m/s at an angle of 31.0° counterclockwise from the original
line of motion. The second ball is initially at rest and after the
collision moves off with a velocity which we wish to describe with
respect to the first ball's original...

Billiard balls A and B of equal mass move at right angles and meet at the...
Billiard balls A and B of equal mass move at right
angles and meet at the origin of an xy coordinate system. Initially
ball A moves along the y axis at 2.0m/s and ball B is moving to the
right along x axis at 3.7 m/s.
After the collision, assumed elastic, ball B moves
along the positive y axis with velocity v'B.
What is the final direction of ball A and what are the
speeds of the two balls?

Two billiard balls of equal mass move at right angles and meet
at the origin of an xy coordinate system. Ball A is moving upward
along the y axis at vA = 1.9m/s , and ball B is moving to the right
along the x axis with speed vB = 5.4m/s . After the collision,
assumed elastic, ball B is moving along the positive y axis(Figure
1) . What is the final direction of ball A? What are their two...

A billiard ball of mass 0.28 kg hits a second, identical ball at
a speed of 7.2 m/s and comes to rest as the second ball flies off.
The collision takes 250 μs.
a. What is the average force on the first ball? Express your
answer with the appropriate units. Enter positive value if the
force is along the first ball's initial speed and negative value if
the force is opposite to the first ball's initial speed.
b. What is...

Two billiard balls with the same mass m move in the direction of
one another. Ball one travels in the positive x-direction with a
speed of V1i, and ball two travels in the negative x-direction with
a speed of V2i. The two balls collide elastically, and both balls
change direction after collision. If the initial speeds of the
balls were v1i=2.0m/s and v2i =1.0m/s, what would be the final
speed and direction of ball two, v2f, in m/s? Thank...

Suppose that you have
several numbered billiard balls on a pool table. The smallest
possible number on the ball is “1”. At each step, you remove a
billiard ball from the table. If the ball removed is numbered
n, you replace it with n balls randomly numbered
less than n. For example, if you remove
the “5” ball, you replace it with balls numbered “2”, “1”, “1”,
“4”, and “3”, where numbers 2, 1, 1, 4, and 3 were randomly...

Two cylinders of identical mass but with different radii roll
down a ramp. In your initial post to the discussion, respond to the
following: Which cylinder gets to the bottom first? Which cylinder
has more total kinetic energy? Why? Now, using the concept of
moment of inertia, explain why two objects rolling down an incline
(even if they have identical masses) roll at different speeds.
