A) Set up the red car with an initial velocity of +3m/s and mass of 3 kg.

B) Set up the blue car with an initial velocity of -2 m/s and mass of 1 kg.

C) Run the simulation and record final velocity and direction of both cars after the collision.

Table

design appropriate table (use lab guidelines, no estimate for error needed in these values) that includes initial and final velocities for both masses, momentum, and kinetic energy. Include sample calculations for calculated quantities.

Analysis

Answer the following questions.

1) Show by calculation if momentum is conserved. Include a percentage error calculation. Use the initial momentum before as the theoretical value for the percentage error calculation. Make a statement.

2) Show by calculation if kinetic energy is conserved. Use the initial kinetic energy before as the theoretical value for the percentage error calculation. Make a statement.

3) Two particles undergo an elastic collision, before the collision particle 1 of mass 1.5 kg and velocity of 12 m/s [right] is on a collision course with particle 2 of mass 3.5 kg and velocity 7.5 m/s [left], Calculate the velocity of the two particles after the collision.
