Question

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:

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?

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

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.

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?

Billiard ball
collision in 2-D. Billiard ball A moving with speed vA=
6.9-m/s in the +x direction strikes an equal-mass ball B initially
at rest.
The two balls are
observed to move off at some unknown angle to the x-axis, ball A
above the x-axis and ball B below.
If v'A = 2.86-m/s at
what angle did ball A go above the x-axis?

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 pool ball is launched in the positive x direction with a
speed of 2.5 m/s. A second, identical pool ball is launched in the
negative x direction with a speed of 1.2 m/s. The two collide in a
glancing collision (not head on) and the second ball is deflected
directly in the positive y direction with a speed of 1.4 m/s.
A. Determine the final velocity of the
first ball. Give your answer in unit vector notation.
B. If...

Billiard ball A of mass mA = 0.130 kg moving with speed vA =
2.65 m/s strikes ball B, initially at rest, of mass mB = 0.140 kg .
As a result of the collision, ball A is deflected off at an angle
of 30.5 ∘ with a speed vA1 = 2.35 m/s .
A.) Taking the x axis to be the original direction of
motion of ball A, write down the equation expressing the
conservation of momentum for the...

A pool ball moves at 2.0 m/s to the right (+x direction) and
hits an identical, stationary ball. After the first ball strikes
the 2nd ball, the first ball's velocity is 1.841 m/s, at an angle
of +23. Assuming an elastic collision (and ignoring friction and
rotational motion), find the struck ball’s (a) speed and (b)
direction after the collision.
Provide your answer for (a) and (b) with three significant digits
of precision, and provide the direction in (b) in...

A billiard ball of mass m = 0.250 kg hits the cushion of a
billiard table and rebounds. The ball’s velocity before it hits the
cushion is 20.0 m/s making an angle of 60.0o with respect to the
normal. The glancing blow leaves the ball with a velocity of 12.0
m/s at 71.0o to the other side of the normal. (a) What is the
magnitude of the change of momentum of the ball? (b) What is the
direction of the...
