BouncyCannonBall

The BouncyCannonBall program adds dynamic events to the Cannonball simulation. using a rootfinder with our integrator to detect contact with the ground, and bounce the cannonball.

For each numerical integration time-step, the simulation program prints:

  1. time (s)
  2. 2D position vector (m)
  3. 2D velocity vector (m/s)

to stdout, in Comma Separated Values (CSV) format.

Building & Running the Simulation Program

Generate the results as follows:

$ make
$ ./BouncyCannonBall > cannon.csv

Plotting the Results

The Python script, plot_trajectory.py is provided to plot the results in cannon.csv using (Python) matplotlib.

Plot the cannon ball trajectory as follows:

$ python plot_trajectory.py
