Question

A billiard ball collides elastically with an identical stationary one. By looking at the collision in the Center of Mass frame, show that the angle between the resulting trajectories in the lab frame is 90 degrees.

Please use the center of mass frame, thanks!

Answer #1

A billiard ball (m=0.17 kg) traveling at 3.25 m/s collides with
an identical billiard ball at rest. After the collision, the first
ball travels at 1.87 m/s at an angle of 23 degrees from the
positive x-axis. What is (a) the speed and (b) the angle of the
second ball?

A hard ball (1.0 kg) is moving 5 m/s and collides with an
identical ball at rest. The collision istotally elastic, and in the
center‐of‐mass frame the balls each deflect by 45 degrees. Find the
velocities after the collision in the lab frame.

A 2.5 g steel ball moving 0.40 m/s collides elastically with a
stationary, identical ball. As a result, the incident ball is
deflected 30.0 degrees from its initial path (remember the 90
degree rule for same masses). 1. Draw a vector diagram showing the
momentum of each ball after the collision 2. What is the velocity
of the incident ball after the collision? 3. What is the velocity
of the struck ball after the collision?
H: m1v0 = m1v1cos theta1...

one billiard ball is shot easy at 2.5 m/s. A second,
identical billiard ball is shot west at 1.2m/s. The balls have a
glancing collision, not a head-on collision, deflecting the sencond
ball by 90 degrees and sending it north at 1.34m/s.
a) what is the speed of the first ball after the collision?
b)what is the direction of the first ball after the collision?

One billiard ball is shot east at 2.5 m/s . A second, identical
billiard ball is shot west at 0.80 m/s . The balls have a glancing
collision, not a head-on collision, deflecting the second ball by
90∘ and sending it north at 1.34 m/s .
What is the speed of the first ball after the collision?
What is the direction of the first ball after the collision?
Give the direction as an angle south of east.

a cue ball is shot at 7m/s east on a pool table toward a
stationary billiard ball with equal mass. after the collision the
billiard ball goes off at an angle 20 degrees north of east. ignore
friction and rotation and assume the collision is elastic. find the
speed of each ball and the direction of the cue ball. (please
include free body diagram and explanations).

One billiard ball with a mass of 0.50 kg is shot east at 2.5
m/s. A second billiard ball with a mass of 0.25 kg is shot west at
2.0 m/s. The balls have a glancing collision, not a head-on
collision, deflecting the first ball by 90° and sending it north at
1.0 m/s.
What are the speed of the second ball after the collision?
What is the direction of the second ball after the collision?
Express your answer as...

One billiard ball is shot east at 3.0 m/s. A second, identical
billiard ball is shot west at 0.8 m/s. The balls have a glancing
collision, not a head-on collision, deflecting the second ball by
90° and sending it north at 1.58 m/s. What are the speed and
direction of the first ball after the collision?
___________ m/s, ___________ ° south of east

A billiard ball with speed of 3.0 m/s in the positive x
direction hits an identical second billiard ball that is at rest at
the origin. After the collision one of the balls has a momentum
with an angle of -24 degrees respect to the positive x axis. The
direction of the momentum of the second ball in degrees is:

One electron collides elastically with a second electron
initially at rest. After the collision, the radii of their
trajectories are 1.00 cm and 2.60 cm. The trajectories are
perpendicular to a uniform magnetic field of magnitude 0.0560 T.
Determine the energy (in keV) of the incident electron.
