Projectiles and Winter Break recharge

The end of the semester was busy hosting a FIRST LEGO League tournament but things are finally now back up to  speed.

We finished the semester studying projectiles and satellites.  One famous physics demonstration in the study of projectiles is the Hunter Monkey demonstration.  Stav produced a great slo-mo video of this demonstration I wanted to share.  The physics question is, “A hunter aims his gun at a monkey in a tree.  If they monkey lets go of the tree branch the instant it hears the gunshot, why does the projectile still hit the monkey?”
