Question

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 collided, they slide together across a rough patch of ground with which their coefficient of kinetic friction is 0.1. How far will they slide across this ground before they come to a stop? d) 4 pts Discuss whether your answer to part a passes the common sense test. Give specific reasons why or why not you think so.

Answer #1

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

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.
a) What is the Initial Momentum of the carts?
b) What is the Final Momentum of the...

A 100kg cart moving at 25m/s rear-ends a 75kg cart moving at
10m/s. The two carts stick together, but during the collision a
10kg wheel on the 100kg cart breaks off and continues moving
forward at 20m/s. Show work for all problems.
1) How fast are the carts going after the collision? (Be sure
that your answer(s) clearly indicate direction as well as
speed.)
2) Is this collision elastic? If yes, explain. If not, calculate
the percentage of the initial...

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....

A red cart with a mass of 250 g is initially moving east at 2.25
m/s. It collides with a blue cart with a mass of 350 g that is
initially moving west at 0.750 m/s. After the collision the kinetic
energy of the two carts together is 0.200 J more than before the
collision, because the spring plunger of one of the carts pushes
them apart during the collision. After the collision, the two carts
are still moving along...

Two frictionless carts collide and stick together in a perfectly
inelastic collision, due to a magnetic or mechanical coupling, on a
one-dimensional track. Cart 1 has mass 200 grams and an initial
velocity of 2 m/s. Cart 2 has mass 900 g, and is initially
stationary. What is the velocity of the two carts together 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?

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.
a) What is the Initial Momentum of the...

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...
