Introduction: In this lab you will investigate the conservation of linear momentum: momentum before an event equals momentum after an event if there is an absence of a non-conservative forces such as friction. The event is this case is a collision between two air track gliders. Two types of collisions will be studied. One is an elastic collision which will not be studied in this lab. after the collision. The second is an inelastic collision where after two objects collide,...

2. For an elastic collision, which equation could you use to predict the final velocity of Cart 2, which is initially stationary, given the initial velocity of Cart 1 and the masses of the two carts? Explain and show your calculation. 3. To study collisions, you will use two devices called photogates. How does a photogate work? Refer to Reference 4 in the FURTHER READING section or other reference.

Background Info: In this experiment you will observe and analyze elastic and inelastic collisions in one dimension and in two dimensions. You will measure the final momentum of a system after it explodes. You will see how both kinds of collision affect the kinetic energy of a system that consists of two frictionless carts. You will determine the momentum of two carts after they collide when one cart is initially stationary. You will analyze the results qualitatively as well as...

In inelastic collisions, when a car that is initially moving collides into a car initially still I know that both cars will move in the direction of the initially moving car at a slower velocity, But would I say momentum has been transferred from car 1 to car 2 or velocity has been transferred from car 1 to car 2. Because obviously, mass is not transferred. And if the initially moving car is more massive than the still car, or...

A bumper car with mass m1 = 107 kg is moving to the
right with a velocity of v1 = 4.6 m/s. A second bumper
car with mass m2 = 98 kg is moving to the left with a
velocity of v2 = -3.2 m/s. The two cars have an elastic
collision. Assume the surface is frictionless.

Two railway cars are on a straight railroad track. The first, with mass 8000 kg, moves slowly at a velocity of 0.05 m/s to the right in the direction of the second car of mass 15000 kg, which is stationary. (a) What is the total momentum (relative to the ground) of both cars together? kg m/s They collide and stick to each other. What is the total momentum right after the collision? For the short times involved, you can take...
