Question

A cart of mass m traveling to the right on a frictionless
track with a speed of 4v0 collides with another cart of mass 2M
traveling to the left with speed v0. If the collision is perfectly
elastic, and carts travel in opposite directions after the
collision, determine the speeds of the two carts immediately after
the collision in terms of m and v0.

Answer #1

a cart of mass m traveling on a horizontal air track with a
speed of ov vo=5.0 m/s collides with a stationary cart of mass 3m.
the carts stick together after the collision. What is the speed of
the carts after the collision?

A runaway rail cart with mass 5000kg traveling on a horizontal
frictionless track with 100ms-1velocity collides with a
similar cart at rest but free to move(no brakes
on). Upon the collision, the two carts attached together (coalesce)
and travel together. Calculate the final velocity of the two carts
system.

A mass M is traveling to the right at 7m/s and collides with
another mass 2M traveling to the left at 4 m/s. The collision is
ELASTIC! Find the two masses velocity after collision and the
percentage of energy lost in the collision.

Two low-friction physics demo carts collide on a horizontal
track. The first cart, with a mass of 0.150 kg , is moving to the
right with a speed of 0.800 m/s . The second cart, with a mass of
0.298 kg , is moving to the left with a speed of 2.27 m/s . The
carts collide in an elastic collision, such that the total klinetic
energy after the collsion is equal to the total kinetic energy
before the collision....

Two carts are rolling to the right along the same level track.
Cart 1 (m1 = 3.81 kg) is in the rear, rolling at a speed of 6.25
m/s and catching up to cart 2, rolling at 3.07 m/s.
Round final results to 3 digits.
a) Cart 1 of course overtakes and collides with cart 2. Velcro
pads on the carts make them stick together during the collision,
after which they both continue rolling right, but at a speed of...

Ball A has a mass of 100 kg; it is traveling to the right at 6.2
m/s. Ball B has a mass of 120 kg; it is traveling to the left at
4.7 m/s.(a) Assume an inelastic collision (they stick together).
Determine velocity at which the two move off together. Give speed
and direction. Pay attention to the + and – signs.(b) Assume they
have a perfectly elastic collision. Determine the speeds and
directions of each of the balls.

Two carts are initially moving to the right on a low-friction
track, with cart 1 behind cart 2. Cart 1 has a speed twice that of
cart 2 and so moves up and rear-ends cart 2, which has twice the
inertia of cart 1.
Q1: Suppose that the the initial speed of cart 2 is vv. What is
the speed of cart 1 right after the collision if the collision is
elastic?
Express your answer in terms of v.
Q2:What...

A small, 300 gg cart is moving at 1.40 m/sm/s on a frictionless
track when it collides with a larger, 4.00 kg cart at rest. After
the collision, the small cart recoils at 0.810 m/s.
What is the speed of the large cart after the collision?

A cart with mass 271 g, moving on a frictionless linear air
track at an initial speed of 1.08 m/s hits an initially stationary
cart of unknown mass. After the collision, the first cart continues
in its original direction at 0.92 m/s. The collision is
elastic.
(a) What is the mass of the second cart?
(b) What is the speed of the second cart?
A block of mass 0.29 kg is placed on top of a light, vertical
spring of...

A small, 200 gg cart is moving at 1.90 m/sm/s on a frictionless
track when it collides with a larger, 5.00 kgkg cart at rest. After
the collision, the small cart recoils at 0.810 m/sm/s .
What is the speed of the large cart after the collision?
Express your answer with the appropriate units.
A 2.2 kgkg block slides along a frictionless surface at 1.4
m/sm/s . A second block, sliding at a faster 4.4 m/sm/s , collides
with the...
