Question

On
a frictionless air track, a 0.165 kg glider moving at 1.50 m/s to
the right collides with and sticks to a stationary 0.265 kg glider.

What is the net momentum of this two-glider system before the
collision? Use coordinates where +x is in the direction of the
initial motion of the lighter glider (Express answer in
kg•m/s)

What must be the net momentum of this system after the
collision (Express answer in kg•m/s)

Use your answers in Parts A and B to find the speed of the
gliders after the collision (Express in m/s)

Is the kinetic energy conserved during the collision?

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...

2. In what direction the glider will go? (left or right)
3.How much energy is lost in the system during the...

Cart 1, with m1= 5.8 kg, is moving on a frictionless linear air
track at an initial speed of 1.8 m/s. It undergoes an elastic
collision with an initially stationary cart 2, with m2, an unknown
mass. After the collision, cart 1 continues in its original
direction at 0.7 m/s. 1) The horizontal component of the momentum
is conserved for cart 1. cart 2. the system of cart 1 and cart 2.
Momentum is not conserved for any of these...

On a linear air track, a 0.13 kg Glider #1 travels at 2.7 m/s to
the right and collides elastically Glider #2 whose mass is 0.3 kg
and is travelling at 0.7 m/s in the opposite direction.
a) Using to the right as a positive direction, calculate the
post collision velocities of both Gliders.
b) Calculate the magnitude of the impulse on either
Glider.
c) Calculate the magnitude of net force on either cart if the
collision lasts 0.05 seconds.

the left with a speed of 2.29 m/s . Suppose the collision is
elastic. Find the magnitude of the final velocity of the 0.155 kg
glider. Find the magnitude of the final velocity of the 0.294 kg
glider.

A car, mass m1 is moving to the right on a frictionless air
track. It collides with a second car, mass m2, which is initially
at rest. Which of the following statements are true? (If A and E
are true, and the others are not, enter TFFFT).
A) If car 1 is much lighter than m2, and the collision is
perfectly elastic, car 1 will continue heading to the right with
nearly its original speed after the collision.
B) If...
