Preview - Investigating Momentum Using Netlogo

Impulse, Momentum, and Kinetic Energy in a Collision between 2 cars.

A NetLogo collision was done with 2 cars and the elasticity at 100%. The before and after pictures are shown below:

Questions

Please answer the questions below.

Set up the mass and velocity values as shown below. Run the experiment. Take data from the experiment in order to fill in the remaining cells to quantify this situation where each car is its own system. 

Initial Velocities:

red(Car0) = 20 (m/s)

brown(Car1) = -20 (m/s)

What was the change in momentum for the red car? Change in momentum is p' - p. Include units on your answer.

How did the impulse on the red car compare to its change in momentum?

What was the change in momentum for the brown car? Change in momentum is p' - p. Include units on your answer.

How did the impulse on the brown car compare to its change in momentum?

How did the impulse on the red car compare to the impulse on the brown car? Comment on magnitude and direction.

How did the ∆p of the red car compare to the ∆p of the brown car? Comment on magnitude and direction.

What was the change in kinetic energy for the red car? Change in KE would be KE' - KE. Include units on your answer.

What was the change in energy for the brown car? Change in KE would be KE' - KE. Include units on your answer.

Let’s look at the collision again and this time, consider that the system to be analyzed consists of the red and brown car combined. Fill in the appropriate numbers below.

What was the change in momentum for the red & brown car system?

What was the total impulse on the red & brown car system?

What was the change in KE for the red & brown car system? Was the total Kinetic Energy conserved in this collision?
