Question

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 the same east-west line. What is the total momentum of the two carts together after the collision? 5. What is the total kinetic energy of the two carts together after the collision? What is the velocity of the red cart after the collision? What is the velocity of the blue cart after the collision?

Answer #1

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.

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 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 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...

A) A block of mass m1=6.0 kg is initially moving at 5.0 m/s to
the right and collides inelastically with an initially stationary
block of mass m2=18.0 kg. The two objects become stuck together.
Find the final velocity of the two blocks.
B) A block of mass m1=6.0 kg is initially moving at 5.0 m/s to
the right and collides elastically with an initially stationary
block of mass m2=18.0 kg.
After the collision, block m2 is moving to the right...

and stick together
c. find the kinetic energy of the system before and after the
Collision

A 2.0 kg mass moving to the east at a speed of 4.0m/s collides
head on in a comletely inelastic collision with a 2.0 kg mass
moving west at 2.0m/s. How much kinetic energy is lost during this
collision?

In a perfectly elastic collision, a 400-g ball moving toward the
east at 3.7 m/s suddenly collides head-on with a 200 g ball sitting
at rest. (a) Determine the velocity of the first ball just after
the collision. (b) Determine the velocity of the second ball just
after the collision. (c) Is kinetic energy conserved in this
collision? How do you know?
please show work on paper

A ball of mass 2.5 kg moving east with a speed of 4.2 m/sec
collides head-on with a 1 kg ball initially moving at 1.7 m/sec to
the west. If the collision is elastic, what will be the speed and
direction of each ball after the collision?
