In a physics experiment, two carts of mass 1.5 kg each are rolled towards each other.  The orange cart has a velocity of 2 m/s and the blue cart has a velocity of -1m/s.  The carts stick together when they collide.

What is the initial momentum of the orange cart?

In a physics experiment, two carts of mass 1.5 kg each are rolled towards each other.  The orange cart has a velocity of 2 m/s and the blue cart has a velocity of -1m/s.  The carts stick together when they collide.

What is the total inital momentum of the system?

Question 6
6.

In a physics experiment, two carts of mass 1.5 kg each are rolled towards each other.  The orange cart has a velocity of 2 m/s and the blue cart has a velocity of -1m/s.  The carts stick together when they collide.

What is the total final momentum of the system?

Question 7
7.

A 9300 kg railroad car A traveling at a velocity of 5 m/s strikes a second railroad car B that weighs 5000 kg at rest. After the collision railroad car A stops moving while railroad car B begins moving in the same direction as the collision.
What is the initial momentum of the system?

Question 8
8.

A 9300 kg railroad car A traveling at a velocity of 5 m/s strikes a second railroad car B that weighs 5000 kg at rest. After the collision railroad car A stops moving while railroad car B begins moving in the same direction as the collision.
At what speed will railroad car B move at?

Question 9
9.

What do you notice about the speeds of the two railroad cars in the above problem? Why do you think this happens?

Question 10
10.

In a physics experiment, two carts of mass 1.5 kg each are rolled towards each other.  The orange cart has a velocity of 2 m/s and the blue cart has a velocity of -1m/s.  The carts stick together when they collide.
What type of collision is this?
Elastic
Inelastic
Explosion
Two skaters begin at rest. Skater 1 has a smaller mass than Skater 2. After they push off each other,...
Skater 1 experiences a greater change in momentum
Skater 1 has a greater velocity than Skater 2
Skater 2 experiences a greater change in momentum
Skater 1 experiences a greater force
