I am looking for the "book" that the Calvin and Hobbs strip that begins in class with a "physics' test in which it says a cannon is fired at a 30 degree angle at a speed of...... six frames later the teacher says turn in your test and calvin puts his head down and says doodlers should not take physics....As a physics teacher I would love to find it and a student award of points has not resulted in its being found do you know where it is?????
