There Are Many Ways to Teach

Brad Delong finds a way to teach vectors after a confrontation with an extremely muddy hill.

3: What happens if, just before the parent reaches the top of the muddy hill, a child at the top of the muddy hill loses control of America's Silliest Dog, which then jumps on the parent who is one step from reaching the top of the hill?

Answer to 3: The sliding force S is 177 pounds. When 40 pounds of dog-force is added, the total force pushing the parent down the hill is 217 pounds--more than the 200 pounds that the friction force can counteract. The parent's feet slip out from underneath, and the parent slides down the hill feet-first belly-down.


Good explaination, even though I dislike his depiction of F as pushing instead of pulling.
