Question

In a game of pool, the cue ball strikes another ball of the same
mass and initially at rest. After the collision, the cue ball moves
at 1.70 m/s along a line making an angle of 25.0° with its original
direction of motion, and the second ball has a speed of 1.40 m/s.
Find **(a)** the angle between the direction of motion
of the second ball and the original direction of motion of the cue
ball and **(b)** the original speed of the cue
ball.

Answer #1

In a game of pool, the cue ball strikes another ball of the same
mass and initially at rest. After the collision, the cue ball moves
at 1.10 m/s along a line making an angle of 15.0° with its original
direction of motion, and the second ball has a speed of 0.850 m/s.
Find (a) the angle between the direction of motion
of the second ball and the original direction of motion of the cue
ball and (b) the original...

In a pool game, the cue ball, which has an initial speed of 4.0
m/s, make an elastic collision with the eight ball, which is
initially at rest. After the collision, the eight ball moves at an
angle of 35° to the original direction of the cue ball.
(a) Find the direction of motion of the cue ball after the
collision.
° (from the original line of motion)
(b) Find the speed of each ball. Assume that the balls have...

In a pool game, the cue ball, which has an initial speed of 7.0
m/s, make an elastic collision with the eight ball, which is
initially at rest. After the collision, the eight ball moves at an
angle of 25° to the original direction of the cue ball.
(a) Find the direction of motion of the cue ball after the
collision (______) I got the 60° which is right.
(b) Find the speed of each ball. Assume that the balls...

In a pool game, the cue ball, which has an initial speed of 2.5
m/s, makes an elastic collision with the 8-ball, which is initially
at rest. After the collision, the 8-ball moves at an angle theta =
14.3 degrees with respect to the original direction of the cue
ball. Assume the pool table is frictionless and the masses of the
cue ball and the 8-ball are equal. The cue ball travels at an angle
of 90 degrees after the...

n a game of pool, a cue ball with an initial velocity of 1.40
m/s directed to the right (along the +x-axis) collides with the
five ball, which has equal mass and is initially at rest. The five
ball then moves at 1.21 m/s at an angle of 30.0° above the +x
direction.
(a) Find the cue ball's final velocity. magnitude direction
below the positive x-axis
(b) Is kinetic energy conserved?

A billiards ball of mass 0.2 kg strikes, another initially
stationary ball of the same mass. The first ball is deflected and
travels at an angle of 60o with its original direction. Its initial
speed was 5.0 m/s and after the collision, it is 3.0 m/s. What are
the magnitude and direction of velocity of the second ball after
collision?

A cue ball (mass = 0.140 kg) is at rest on a frictionless pool
table. The ball is hit dead center by a pool stick, which applies
an impulse of +1.40 N · s to the ball. The ball then slides along
the table and makes an elastic head-on collision with a second ball
of equal mass that is initially at rest. Find the velocity of the
second ball just after it is struck. m/s

In a pool game, a cue ball traveling at 0.75 m/s hits the
stationary eight ball. The eight ball moves off with a velocity of
0.25 m/s at an angle of 37 degrees relative to the cue ball's
initial direction. Assuming that the collision is inelastic, at
what angle will the cue ball be deflected, and what will be its
speed?

A billiard ball moving at 5.80 m/s strikes a stationary ball of
the same mass. After the collision, the first ball moves at 4.97
m/s, at an angle of 31.0° with respect to the original line of
motion.
(a) Find the velocity (magnitude and direction) of the second
ball after collision.
______ m/s
° (with respect to the original line of motion, include the sign of
your answer; consider the sign of the first ball's angle)(b) Was
the collision inelastic...

A cue ball (mass = 0.170 kg) is at rest on a frictionless pool
table. The ball is hit dead center by a pool stick, which applies
an impulse of +1.20 N · s to the ball. The ball then slides along
the table and makes an elastic head-on collision with a second ball
of equal mass that is initially at rest. Find the velocity of the
second ball just after it is struck.
