3.
Two balls collided on a smooth horizontal surface. Assume the
collision is elastic, please find the velocities after collision.
We know the mass of ball 1 is 5.0 kg, ball 2 is 1.0kg. Before
collision ball 1 is at rest and ball 2 has a velocity of
3.0m/s.

Answer #1

Two gliders, A and B undergo an elastic collision along a
horizontal air track. (a) Show that the velocities of the gliders
follow the relationship: , where the subscripts 1 and 2 denote the
speeds before and after the collision, respectively, and the
subscripts A and B refer to each glider. (b) If glider B is
initially at rest and has a mass of 0.20 kg, and glider A moves at
3.0 m/s before the collision at -0.50 m/s after...

Two billiard balls of identical mass move toward eachother.
Assume that the collision between them is perfectly elastic. If the
initial velocities of the balls are 30 cm/s and -20 cm/s, assume
friction and rotation are unimportant.
a) Derive an expression for the velocity and then calculate the
velocities of the balls after the collision?
b) Find the final velocity of the two balls if the initial
velocity of -20 cm/s has a mass equal to one half of the...

Two rubber balls undergo an elastic collision. Ball 1 has a mass
of 10 kg and an initial velocity of 5 m/s in the positive x
direction. Ball 2 has a mass of 10 kg and is
stationary. What is the final velocity of the two
balls, v1f, and v2f?

When a cue ball strikes the 8-ball, we can assume that the
collision is elastic. An 8-ball has a mass of 0.160 kg, and we have
made a special cue ball, with a lead core, to have a mass that is 3
times as much as the 8-ball's mass, or 0.480 kg. Let's say this
heavy cue ball, initally moving at 1.5 m/s, strikes the 8-ball, and
the 8-ball's subsequent velocity is in the same direction as the
initial velocity...

Two large balls roll over a smooth surface and collide. They are
made of a super hard material so there is no deformation. Ball 1
has a mass ?1 of 2.00 ?? and travels with an initial velocity of
10.0 ?/?. Ball 2 has a mass ?2 of 5.00 ?? and travels with an
initial velocity of 1.42 ?/?. A tracking system captures the
collision data and is shown below. After the collision, what are
the speeds of the two...

A ball with a mass of 1.1 kg is initially at rest. It is struck
by a second ball having a mass of 1.3 kg, initially moving with a
velocity of 3.5 m/s toward the right along the x axis. After the
collision, the 1.3 kg ball has a velocity of 2.7 m/s at an angle of
35? above the x axis in the first quadrant. Both balls move on a
frictionless, horizontal surface. Do not assume that the collision...

Ball 1 rests on a smooth surface, when Ball 2, whose mass is
one-third of the mass of Ball 1, traveling horizontally at 20 m/s,
strikes Ball 1. As a result of the collision, Ball 2 is deflected
30 degrees above its original direction of motion, while Ball 1
acquires a velocity directed 45 degrees below the horizontal.

Between a steel ball and a glass ball, there is a
straight, central, fully elastic collision. The glass ball is ahead
of the heist
at rest and after the impact, it has a speed of 9.0 m/s. Calculate
the speeds of the steel ball before and after the shock, if
the mass of the steel ball is three times the mass of the glass
ball.
Answer 6.0m/s and 3.0m/s

Two billiard balls with identical masses and sliding in opposite
directions have an elastic head-on collision. Before the collision,
each ball has a speed of 23 cm/s. Find the speed of each billiard
ball immediately after the collision.
Ball 1 =
cm/s
Ball 2 =
cm/s
