Question

1) You collide two cartselastically. One 2-kg cart is moving to the right at 3 m/s, and the other is a 3-kg cart that is heading to the left at 4 m/s. a) What are the final velocities of each cart? b) What are the final and initial total momentums? How do they compare? c) What are the final and initial total kinetic energies? How do they compare?

2) You collide two carts inelastically. One 2-kg cart is moving to the right at 3 m/s, and the other is a 3-kg cart that is heading to the left at 4 m/s. a) What are the final velocities of each cart? b) What are the final and initial total momentums? How do they compare? c) What are the final and initial total kinetic energies? How do they compare?

Answer #1

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....

1.Two identical carts are moving on a frictionless surface with
constant velocity v (cart 1 v cart 2 -v). After they collide
elastically what is their final velocities?

Please explain.

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

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!

Cart C is moving to the right at 3 m/s toward cart D, which is
at rest. The cart collide in an elastic collision, and after the
collision cart D is moving to the right at 2.4 m/s. The mass of
cart C is 2kg and the mass of cart D is a 3kg.
What is the total momentum of the cart C + cart D system before
the collision?
What is the speed and direction of cart C after...

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...

A cart of mass 500 kg experiences an impulse of 11N * s.
Afterwards the cart is seen to move with a velocity of 12 m/s and
is moving to the left.
a. What is the final momentum of the cart (remember the
signs!)?
b. What is the carts initial momentum and initial velocity
(Again, remember your signs!!)?

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...

A ball with a mass of 2 kg is initially moving to the right with
a speed of 3 m/s. It collides with a 5 kg ball moving to the left
with a speed of 1 m/s. The balls collide partially elastically: 70%
of the initial kinetic energy of the system is conserved in the
collision. Find the final velocity of each ball. The balls move
only along the x-axis. Show your work.
