Question

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. What is the final speed of the 0.150 kg cart? What is the final speed of the 0.298 kg cart?

Answer #1

Two carts are on an air-track where friction is negligible. The
Incident Cart is moving at an initial velocity of 0.44374 m/s, the
target cart is at rest. The Incident cart has a mass of 490.3 g and
the target cart has a mass of 497.4 g. The final velocity of the
incident cart is 0.043994 m/s and the final velocity of the target
cart is 0.001001 m/s. The collision is elastic.

Two carts are on an air-track where friction is negligible. The
Incident Cart is moving at an initial velocity of 0.25080m/s, the
target cart is at rest. The Incident cart has a mass of 995.8 g and
the target cart has a mass of 490.3 g. The carts stick together,
the final velocity after collision is 0.077302 m/s. The collision
is considered inelastic.

Imagine two carts of equal mass (m = 1.0 kg) collide. If cart
one is initially moving at 10 m/s and the other cart is stationary,
calculate the final speed of each mass after they have a 100%
elastic collision. Please show all work!

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.

2 air carts collide and stick together. cart one is M1
= 0.755 kg and initial speed of 0.435 m/s the cart to right is
initially at rest with mass m2= 0.300kg.
a.find the velocity of the center of mass before the carts Collide
and stick together
b. find the velocity of the center of mass after the carts Collide
and stick together
c. find the kinetic energy of the system before and after the
Collision

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?

1.
Assume the cart has a mass of m, and that the carts are oriented so
that their velcro bumpers face each other. one of the carts is
placed on middle of the track and the other on the far left of the
track. suppose you push the cart gently on the left side toward the
cart at rest so that the carts collide.
mass of cart is .05123 kg
a) if the velocity of the moving cart is v...

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...

Two carts of mass 50 kg have a collision. Before the collision,
the first cart was travelling to the right at 4 m/s, and the 2nd
cart was travelling to the left at 3 m/s. After the collision, the
carts stick together. a) 10 pts What is the velocity of the carts
immediately after the collision? b) 6 pts How much kinetic energy
was lost in the collision? Where did this energy go? c) 10 pts
After the carts have...

Consider a collision between two carts, one of mass mA= 5 kg and
the otherof mass mB= 7 kg, on a frictionless track. (A). Find the
final velocity of Cart A, if both objects are initially moving in
opposite directions toward each other at 12 m/s, and Cart B
completely stops due to the collision. (B). Is this an elastic or
inelastic collision? Why?
