Question

A cue ball traveling at 4.0 m/s makes a glancing, elastic collision with a target ball of equal mass that is initially at rest. The cue ball is deflected so that it makes an angle of 30° with its original direction of travel.

Find the speed of each ball after the collision.

cue ball?

target ball?

Answer #1

A cue ball traveling at 8.0 m/s makes a glancing, elastic
collision with a target ball of equal mass that is initially at
rest. The cue ball is deflected so that it makes an angle of 30°

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 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...

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...

A 0.50 kg cue ball makes a glancing blow to a stationary 0.50 kg
billiard ball. After the collision the cue ball deflects with a
speed of 1.2 m/s at an angle of 30.0° from its original path.
Calculate the original speed of the cue ball if the billiard ball
ends up travelling at 1.6 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?

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 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...
