Question

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 the collision, what is the mass of glider A and the final velocity of glider B?

Answer #1

mass of glider A is 0.14 kg

final velocity of glider B is 2.5 m/s

Two particles, ?1 and ?2, undergo a glancing elastic collision.
Initially mass ?1 moves along the negative ?-direction and ?2 along
the positive ?-direction, both with speed ?? . After the collision
?1 moves along the negative ?-direction. Given that ?2 = 8 ?1, find
the magnitudes of the velocities of both particles in terms of ?? ,
and the direction of mass ?2.

Two gliders collide head-on. In this case the bumpers work very
well and the collision is elastic. Initially the heavy glider has a
speed of 2.5 m/s and the light glider a speed of 1.8 m/s. The heavy
glider’s mass is 0.300 kg and the light glider’s mass is 0.200 kg.
You may treat the light glider as going in the +x
direction initially and the heavy glider going in the –x
direction. What is the velocity of the light...

on an air track, a 2.25kg glider moving at 2.10m/s north has an
elastic collision with a glider moving at 1.50 m/s south. The
second glider has 2.40 times the mass of the first glider. What is
the final velocity, the velocity after the collision of the first
glider in m/s? What is the velocity of the second glider in
m/s?

In a lab experiment, two identical gliders on an air track are
held together by a piece of string, compressing a spring between
the gliders. While they are moving to the right at a common speed
of 0.500 m/s, one student holds a match under the string and burns
it, letting the spring force the gliders apart. One glider is then
observed to be moving to the right at 1.300 m/s. (the string and
spring both have negligible mass).

Two blocks move along a linear path on a nearly frictionless air
track. One block, of mass 0.112 kg, initially moves to the right at
a speed of 5.40 m/s, while the second block, of mass 0.224 kg, is
initially to the left of the first block and moving to the right at
7.40 m/s. Find the final velocities of the blocks, assuming the
collision is elastic.

1) The kinetic energy of a .500 kg glider(glider A) moving on an
air track is 1.00 J. Find the speed of glider A.
2)Two gliders are moving toward each other. Glider A has a mass
of 500 g and is moving with a velocity of 40 cm/s.
Glider B has a mass of 400 g and is moving with a velocity of -50
cm/s. After a head-on collision, glider A moves with a velocity of
10 cm/s and glider...

Two billiard balls of equal mass undergo a perfectly elastic
head-on collision.
If one ball's initial speed was 2.10 m/s , and the other's was
3.80 m/s in the opposite direction, what will be their speeds after
the collision?

A 0.155-kg glider is moving to the right on a frictionless,
horizontal air track with a speed of 0.81 m/s. It has a head-on
collision with a 0.310-kg glider that is moving to the left with a
speed of 2.26m/s. Find the final velocity (magnitude and direction)
of each glider if the collision is elastic.

b. 0.310-kg glider magnitude---m/s

Two gliders are moving toward each other. Glider A has
a mass of 500 g and is moving with a velocity of 40 cm/s. Glider B
has a mass of 400 g and is moving with a velocity of -50 cm/s.
After a head-on collision, glider A moves with a velocity of 10
cm/s and glider B moves with a velocity of 50 cm/s.
A.) calculate the total initial and final momenta of the two
gliders. Determine whether linear momentum...
